Question

PQRS is a parallelogram in which P=120. Find the measure of the angles Q,R,and S

Answer 1

Answer:

Since in llgm opp. angles are equal therefore angle P = angle R = 120°

In a llgm the sum of adjacent angles are 180°

therefore angle P + Angle S = 180°

Angle S = 180° - 120°

Angle S = 60°

Similarly, Angle S = Angle Q ( since in llgm opp. angles are equal )

therefore Angle Q = 60°

Answer 2

Step-by-step explanation:

Since in Ilgm opp. angles are equal therefore angle P = angle R = 120°

In a Ilgm the sum of adjacent angles are 180°

therefore angle P + Angle S = 180°

Angle S = 180° - 120°

Angle S = 60°

Similarly, Angle S = Angle Q (since in Ilgm opp. angles are equal)

therefore Angle Q = 60°
