Question

Two vertices of an isosceles triangle are (2, 0) and (2, 5). Find the third vertex if the length of the equal sides is 3.

Answer 1

Two vertices of an isosceles triangle are A(2, 0) and B(2, 5). Let C(x,y) be the third vertex

Also we are given that

The third vertex is (3.65, 2.5) or (0.35, 2.5)
