Urgent answer please

Answer 1

Answer:

join OA and OB

Now for Triangle OAP and OPB

OA = OB both are radius

AP = BP since P is mid point

OP is common.

so OAP is Congruent to OBP

therefore angle OPA = OPB

but there sum is 180 deg

therefore both are 90 deg

so proved that OP is perpendicular to AB
