NCERT Solutions for Class 9 Maths Chapter 4 - Linear Equations in Two Variables

In Chapter 4, students get familiar with coordinate geometry and learn how to plot the graph of a linear equation with two variables. Linear equations in two variables demonstrate the connection between two variables and how this relates to their graphical representation. These equations come with two solutions, producing a line when plotted. NCERT solutions for class 9 maths Chapter 4 linear equations in two variables are created with exercises based on writing linear equations, discovering their answers, plotting them, and seeing how they form lines parallel to x and y axes.

Topics Covered

  • Recall of linear equations in one variable.
  • Introduction to two-variable equations.
  • In the case of linear equations with two variables, prove that there are infinitely many solutions, and justify writing them as ordered pairs of real numbers, plotting them and showing that they seem to line up.
  • Real-life examples, such as problems involving ratios and proportions, are simultaneously available with both algebraic and graphical solutions.

An equation is simply the mathematical way to describe a relationship between two variables. The variables may be physical quantities, perhaps temperature and position for instance, in which case the equation tells us how one quantity depends on the other, so how the temperature varies with position.

The simplest kind of relationship that two such variables can have is a linear relationship. This means that to find one quantity from the other you multiply the first by some number, then add another number to the result. Put mathematically, if we call the quantities x and y, then they are related by the equation? y = mx + c, where we can choose any values for m and c.

This is a linear equation. Fortunately, in real physical problems, quantities often are related linearly, so this equation is very commonly used.This chapter covers- Recall of linear equations in one variable. Introduction to the equation in two variables.

NCERT Solutions for Class 9 Maths Chapter 7 - Triangles

Chapter 7 of NCERT Maths Class 9 Solutions covers triangles. This chapter explains the properties of triangles, such as inequalities, congruence, and rules of congruence. During the exercise questions, students are taught how to apply congruence rules.

Topics Covered

  • Triangles can be congruent under different conditions.
  • According to SAS Congruence, if two triangles have any two sides and the included angle of one triangle equals any two sides and the included angle of the other triangle, they are congruent.
  • Similarly, ASA Congruence states that if two triangles have any two angles and the included side of one triangle equal to any two angles and the included side of the other triangle, then they can be said to be congruent. SSS Congruence states that if the three sides of one triangle are equal to the three sides of another triangle, they are considered congruent. Furthermore, two right triangles can be considered congruent if their hypotenuse and a side (in respective order) are equal in both triangles.
  • The angles opposite to equal sides in a triangle are also equal. Similarly, opposite to equal angles in a triangle lay sides which are also equal. Moreover, Triangle Inequalities hold true when it comes to relation between angle and facing side; thereby proving inequalities in a triangle.

Similarity is some degree of symmetry in either analogy and resemblance between two or more concepts or objects. In philosophy, similarity is defined as sharing properties or characteristic traits Looking around you will see many objects which are of the same shape but of same or different sizes.

For example, photographs of different sizes developed from the same negative are of same shape but different sizes, the miniature model of a building and the building itself are of same shape but different sizes. All those objects which have the same shape but different sizes are called similar object.

Definitions, examples, counter examples of similar triangles.

  1. If a line is drawn parallel to one side of triangle to intersect the other two sides in distinct points the other two sides are divided in the same ratio.
  2. If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.
  3. If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
  4. If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
  5. If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.
  6. If a perpendicular is drawn from the vertex of the right angle of right to the whole triangle and too each other.
  7. The ratio of the areas of two similar triangles is equal to the ratio of the squares on their corresponding sides.
  8. In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
  9. In a triangle, if the square on one side is equal to sum of the squares on the other two sides, the angles opposite to the first side is a right triangle.

NCERT Solutions for Class 9 Maths Chapter 8 - Quadrilaterals

In Chapter 8, you will learn about quadrilaterals and their various properties. A quadrilateral is a figure obtained by joining four distinct points on a plane. Students are provided with in-depth knowledge about the topic in this chapter.

Topics Covered

  • (Prove) The diagonal divides a parallelogram into two congruent triangles.
  • (Motivate) In a parallelogram, opposite sides are equal and conversely.
  • (Motivate) In a parallelogram, opposite angles are equal and conversely.

  • (Motivate) In a triangle, the line segment joining the midpoints of any two sides is parallel to the third side and (motivate) its converse.

There are three topological types of quadrilaterals convex quadrilaterals concave quadrilaterals and crossed quadrilaterals. A quadrilateral with two sides parallel is called a trapezoid, whereas a quadrilateral with opposite pairs of sides parallel is called a parallelogram.

A special type of quadrilateral is the cyclic quadrilateral, for which a circle can be circumscribed so that it touches each polygon vertex. Another special type is a tangential quadrilateral, for which a circle can be inscribed so it is tangent to each edge. A quadrilateral that is both cyclic and tangential is called a bicentric quadrilateral.

(Prove) The diagonal divides a parallelogram into two congruent triangles. (Motivate) In a parallelogram opposite sides are equal and conversely. (Motivate) In a parallelogram opposite angles are equal and conversely. (Motivate) A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and equal. (Motivate) In a parallelogram, the diagonals bisect each other and conversely. (Motivate) In a triangle, the line segment joining the mid points of any two sides is parallel to the third side and (motivate) its converse.

NCERT Solutions for Class 9 Maths Chapter 9 - Areas of Parallelograms and Triangles

You have studied the concept of quadrilaterals and triangles, and now you will study specific quadrilaterals, viz. parallelograms and triangles in relation to the calculation of their area. In this chapter, students learn the formula for area calculation and the relationship between different geometric figures.

Topics Covered

  • The diagonal of a parallelogram serves as a divider, forming two congruent triangles.
  • Opposite sides and angles in the quadrilateral are equal, a defining feature of a parallelogram.
  • Moreover, the diagonals bisect each other in such a case, as well as the line segment joining the midpoints of any two sides parallel to the third side.

First of all, obviously, equally oriented, congruent parallelograms have the same area, because they can be made to cover each other. An examination of two symmetric parallelograms, which have the same area, because they will cover each other on reflection, is a step in the right direction. The area of a parallelogram is obtained by sub-division into two congruent triangles. The area of a trapezoid also involves its being cut up by a diagonal into two triangles.

Review concept of area, recall area of a rectangle. Prove Parallelograms on the same base and between the same parallels have the same area. Motivate Triangles on the same base and between the same parallels are equal in area and its converse.

  8. (Motivate) The sum of either pair of opposite angles of a cyclic quadrilateral is 1800 and its converse.

The circle has been known since before the beginning of recorded history. It is the basis for the wheel which, with related inventions such as gears, makes much of modern civilization possible. In mathematics, the study of the circle has helped inspire the development of geometry and calculus.

Circles are simple closed curves which divide the plane into an interior and an exterior. The circumference of a circle is the perimeter of the circle, and the interior of the circle is called a disk. An arc is any connected part of a circle. A circle of infinite radius is considered to be a straight line. A circle with zero radius is considered as a point.

As these problems are based on real-life incidents, students are more likely to be interested in solving them.

Topics Covered

  • This course focuses on empirical probability using history, repeated experiments, and observed frequency.

(Much time will be devoted to group and individual activities to motivate the concept;

In investigating weighing, and sorting and finding an efficient code, you may note a common thread. In each case, and in many others that we will encounter later, we start with a (usually large) number of possible situations, and are interested in determining the true situation from among them. Thus we have devised schemes for doing so in the contexts mentioned.

Probability theory, which by the way was developed initially in the study of gambling schemes, is intended to provide a framework for modeling problems of this kind, with the aim of providing information about what we can “expect” to happen in each context.

This is done by defining a Sample Space whose points or elements are the possible situations, each one of which is given a weight or probability according to the proportion of the time we expect it to be the true situation.Then we determine what to “expect” as the answer to some question, by representing the answer as a function defined on the points of the sample space, and averaging that function over them.

In most contexts, including gambling and all that we have considered so far, the potential situations can be represented by strings of binary bits (or ternary symbols, in the case of weighing). In the following discussion we assume that our sample space consists of points each of which is such a bit string.
