Question

Show that the points (7,5), (2, 3) and (6, -7) are the vertices of a right angled triangle. Find its
area.
​

Answer 1

Step-by-step explanation:

let these point be A(7,5) B(2,3) and C(6,-7)

find distance between these point

AB = ?

BC = ?

CB = ?

by using formula

D = √[ (x1 - x2)^2 + ( y1 - y2)^2 ]

there distance will be different then

take a square of the biggest side prove it equal to the sum of another 2 side's square. As,

(hypotenuse)^2 = (perpendicular)^2 + (base)^2
