Q14 of 184 Page 10

Determine the type (isosceles, right angled, right angled isosceles, equilateral, scalene) of the following triangles whose vertices are:
(0, 2), (7, 0), (2, 5)

Given points are A(0, 2), B(7, 0) and C(2, 5).

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

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

⇒

We got AB≠BC≠CA

∴ The given points form a scalene triangle.

Prove that the points (3, 4), (8, - 6) and (13, 9) are the vertices of a right angled triangle.
