Question

If an isosceles triangle one of the base angle is 60. find the vertical angle.solve

Answer 1

The vertical angle is 60 degree too.

Hint:

One of the base angle is 60 degree.

Other base angle is 60 degree too.

Vertical angle will be 180 - 2 x Base angle = 180- (2 x 60) = 180-120=60

The vertical angle is 60 degree too.
