Question

- In the adjoining figure, ABCD is a parallelogram and <A = 120°. If the
bisectors of <A and <B meet at a point P, show that <APB is a right
angle.​

Answer 1

Measure of angle B = 180-120=60

A bisector divides the angle into 2 equal parts

So in triangle APB

A = 60

B = 30

P = 180-(60+30)

= 90
