Q) Show that the points (-2, 3), (8, 3) and (6, 7) are the vertices of a right-angled triangle.

Ans: Let’s plot these points on graph, we get:

Show that the points (-2 3)

Then, AB = 10,

BC = √(4 + 16) = 20

AC = (64 +16) = 80

Since, (10) = (20) 2  + (80) 2

Or AC2 = AB+ BC2

Therefore, triangle ABC is a right-angled triangle.
