Question

AB is the diameter of the circle with centre O and P is any point on the circle such that
AP=BP. Find the measure of angle A and angle POA.
​

Answer 1

Answer:

Draw a circle of known radius.

Mark the center "O" and diameter "AB".

Mark a point "P" on circle such that "PA=PB".

Given,

PA=PB

∠POA=∠POB

∠POA=90°

When we measure the ∠A we get,

∠A=55°

∠P=35 °
