=(y−1)

Hence, the two lines are =

y=−x+1 and y=x+1

Equation of angle bisectors of these lines

x=0 and y=1

Intersection between the 3 lines is

A(0,3),B(0,1),C(2,1)

It can be seen that as the points A and B lie on y-axis only and BC is parallel to x-axis. Hence, △ABC is a right angled triangle.
