Question

IN PARALLOLELGRAM PQRS THE SUM OF ANGLE P AND ANGLE R IS 80 DEGREE FIND THE MEASURE OF ANGLE P, ANGLE Q AND ANGLE S

Answer 1

Answer:

In a parallelogram measure of opposite angles is equal.

therefore Angle P = angle R

But P+R=80°

P+P=80

P = 40

also R= 40

Also P + S =180 (linear pair)

40+S=180

S = 140

also Q=S (opposite Angles )

therefore Q = 140°
