Question

please give me the correct answer of this​

Answer 1

Step-by-step explanation:

anglePOR + angle POQ = 180 (linear pair angles )

divide both side by 2

anglePOR /2 + anglePOQ/2 = 180/2

anglePOB + angle POA = 90 (OB and OA bisect POR And POQ)

and

( anglePOR + anglePOQ = angleAOB )

angle AOB = 90°
