Question

□PQRS is a parallelogram. write the sum of measure of angle P and angle Q

Answer 1

angle P +angleQ =180°

because...
adjacent angles of parallelogram are supplementary.

hope it will be helpful for you..
please mark me as brainliest..

Answer 2

angle P + angle Q = 180°

opposite sides of the parallelogram are parallel i.e. PS ll RQ , PQ is transversal

hence ,angle P and angle Q are interior angles

sum of interior angles is 180°
