Question

□PQRS is a parallelelogram.If angleP=60° then find angleQ

Answer 1

in a parallelogram the opposite sides are equal and alternate interior angles are equal

so angle p = angle r = 60

so parallelogram is a quadrilateral that is sum of all angles is 360

angle p + angle q  + angle r + angle s = 360

60 + angle p + angle r + 60 = 360

therefore taking  angle p and angle r as x

x + x = 300

2x = 300

x = 150

Answer 2

PQRS is Parrallelogram.

therefore, Oppostie sides are Parallel.

therefore, Angle P ➕ Angle of Q = 180°
60➕Q=180°
Q=180-60
Q=120°
