A triangle is a simple closed curve made up of three-dimensional lines. It has three vertices, three sides, and three angles.

Classification of triangles based on sides

• A triangle that has three unequal sides is known as scalene triangle.
• A triangle that has two equal sides is known as isosceles triangle.
• A triangle that has three equal sides is known as equilateral triangle.

Classification of triangles based on angles

• If each angle is less than 90°, the triangle is called an acute-angled triangle.
• If anyone's angle is a right triangle, then the triangle is called a right-angled triangle.
• If anyone's angle is greater than 90°, then the triangle is called an obtuse-angled triangle.

Solved Examples

Q1. What are the properties of a triangle?

1. A triangle is a simple closed curve made of 3 lines.
2. triangle has 3 vertices
3. A triangle has 3 angles
4. All of them

Ans. Correct option is 4

A triangle has all the properties as mentioned in the options.

Q2. A________connects a vertex of a triangle to the mid point of opposite sides.

1. side
2. angle
3. vertex
4. median

Ans. Correct option 4

A median cuts a side of a triangle on which it falls into two equal halves.

Q3. How many medians can a triangle have?

1. 4
2. 2
3. 3
4. 1

Ans. Correct option is 3

Since there are 3 vertices their are 3 medians.

Q4. Can we form an exterior angle on every vertex of a triangle?

1. No
2. Yes
3. Might be
4. None of them

Ans. Correct option is 2

By extending any side of a triangle, an exterior angle can be formed.

Q5. Can you have a triangle with all the angles less than 60o?

1. No
2. Yes
3. Might be
4. Can’t say

Ans. Corrrect option is 1

Sum of all the angles of a triangle has to be equal to 180o. If the angles measure less than 60o each, there would be no triangle.

Q6. The sum of the lengths of any two sides of a triangle is______than the 3rd side of triangle.

• less
• equal
• more
• None of them

Ans. Correct option is 3

It is one of the properties of a triangle.

Q7. Define hypotenuse?

1. The side opposite to an acute angle.
2. The side opposite to a right angle.
3. Another name for obtuse angle.
4. None of them

Ans. Correct option is 2

Q8. Pythagoras property hold only if the triangle is__________.

1. Right angled triangle
2. Obtuse angled triangle
3. Acute angled triangle
4. None of them

Ans. Correct option is 1

In the Pythagoras theorem, a hypotenuse is required which is only available in a right angled triangle.

Q9. What do you mean by perimeter in triangle?

1. The sum of all the 3 angles of a triangle.
2. The sum of all the 3 sides of a triangle.
3. The sum of all the sides and angles of a triangle.
4. None of them

Ans. Correct option is 2

Perimeter is the sum of all the sides of a triangle.

Q10. Can a triangle have two right angles?

1. Yes
2. No
3. Might be
4. Can’t say 25

Ans. Correct option is 2

Sum of 3 angles of a triangle is 180.
