Question

Triangle ABC has vertices (4,-1), B(5,6) and C(1,3). Prove using coordinate geometry that ABC is an isosceles right triangle.

Answer 1

the coordinates of vertices triangle ABC are (4,-1), B(5,6) and C (1,3) prove that triangle ABC is an isosceles right triangle.

Answer 2

Explanation:

first find distance between ab

then between bc

then ac

in isosceles triangle 2 sides are equal

so if two sides means the distance we find are same

the givan triangle is isosceles
