The Distance Formula, frequently encountered in Class 10 mathematics, serves to compute the distance between two points in coordinate geometry. Understanding its fundamental concepts is crucial, given its significance in various applications, such as estimating distances between moving objects or locations. List of Distance Formulas for Class 10:
Distance between Points (x 1 , y 1 ) and (x 2 , y 2 ):D=[ (x 2 −x 1 ) 2 +(y 2 −y 1 ) 2 ] 1/2
Distance of a Point P(x, y) from the Origin O(0,0):D= (x 2 +y 2 )
Coordinates of a Point dividing Line Segment AB(x 1 , y 1 ) and B(x 2 , y 2 ) in ratio m 1 : m 2 :( (m 1 x 2 +m 2 x 1 ) /(m 1 +m 2 ) , (m 1 y 2 +m 2 y 1 ) /(m 1 +m 2 ) )
Midpoint of Line Segment AB(x 1 , y 1 ) and B(x 2 , y 2 ):( (x 1 +x 2 )/2 , ( y 1 +y 2 )/2 )
Applications of Distance Formula
The distance formula finds applications in both algebra and geometry: Navigation systems utilize the distance formula, derived from Pythagoras' theorem, to determine coordinates on sea and land, forming an integral part of navigation technology. In coordinate geometry, it aids in identifying the shape of a given quadrilateral. If the sides are equal, it implies a square. Additionally, it's instrumental in finding the shortest path between two points.
Distance Formula Solved Examples
Example 1: Use the distance formula to find the distance between points P(-5,7) and Q(-1,3).
Solution:
Distance between Points (x 1 , y 1 ) and (x 2 , y 2 ):D=[ (x 2 −x 1 ) 2 +(y 2 −y 1 ) 2 ] 1/2
D= (−1−(−5)) 2 +(3−7) 2 = 4 2 +(−4) 2 = 32
Example 2: Determine the coordinates of the point dividing the line segment joining (4, –2) and (7, 4) in the ratio 2:1 internally.
Solution: Let the coordinates be (x, y).
x= (m 1 x 2 +m 2 x 1 ) / m 1 +m 2 = 3 4∗2+7∗1 =5 y= ( m 1 y 2 +m 2 y 1 ) / m 1 +m 2 = 3 −2∗2+4∗1 =0 Hence, the coordinates are (5, 0).Strategies for Memorizing the Distance Formula
