all the formulas of class 10 maths chapter 7 cordinate geometry ​

Answer 1

Answer:

•Distance Formula

Distance between Two Points on the Same Coordinate Axes

The distance between two points which are on the same axis (x-axis or y-axis), is given by the difference between their ordinates if they are on the y-axis, else by the difference between their abscissa if they are on the x-axis.

Points on the Coordinate Plane

Distance AB = 6 – (-2) = 8 units

Distance CD = 4 – (-8) = 12 units...

•Distance between Two Points Using Pythagoras Theorem

Distance between two point using Pythagoras theorem

Finding distance between 2 points using

Pythagoras Theorem

Let P(x1, y1) and Q(x2, y2) be any two points on the cartesian plane.

Draw lines parallel to the axes through P and Q to meet at T.

ΔPTQ is right-angled at T.

By Pythagoras Theorem,

PQ2 = PT2 + QT2

= (x2 – x1)2 + (y2 – y1)2

PQ = √[x2 – x1)2 + (y2 – y1)2]
