Question

In the figure out is the centre of the circle and PA=PB find angleOPA

Answer 1

Join OA and OB

In △OAP and △OBP

OA=OB(radii of same circle)

AP=BP(Given)

OP=OP(Common)

These triangles are congruent by SSS rule

Angle OPA = Angle OPB(cpct)

Angle OPA+Angle OPB=180(linear pair)

Angle OPA = Angle OPA=180

2angleOPA =180

Angle OPA = 90°
