Q. 14 A

# Determine the type (isosceles, right angled, right angled isosceles, equilateral, scalene) of the following triangles whose vertices are:(1, 1), (- ), (- 1, - 1)

Given points are A(1, 1), B(- √3, √3) and C(- 1, - 1).

Let us find the distance between sides AB, BC and CA.

We know that the distance between the two points (x1, y1) and (x2, y2) is

We got AB = BC = CA

The given points form an equilateral triangle.
