Question

(1,1).
Without using Pythagoras theorem, show that the points A (0,4), B (1, 2) and C (3, 3) are
the vertices of a right angled triangle.
(Anand (23) are the vertices of a rectangle.​

Answer 1

Use slope method
Slope of AB = -2
Slope of BC = 1/2
Slope of CA = -1/3
Now slope of AB x Slope of BC = -1
This implies AB is perpendicular to BC
Hence, triangle is right angle triangle.
