Q. 14 E5.0( 1 Vote )

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

(1, 2), (3, 0), (- 1, 0)

Answer :

Given points are A(1, 2), B(3, 0) and C(- 1, 0).



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 .






AB = 4










CA = 4


We got AB = BC = CA


The given points form an equilateral triangle.
