Question

In a parallelogram ABCD, if angle A =110° ,find
angle B, angle C, angle
D.​

Answer 1

Answer:

In parallelogram opposite angles are equal

therefore, angle A = angle C = 110⁰

and in parallelogram sum of adjacent sides is equal to 180⁰

therefore, angle A + angle B = 180⁰

180 - 110 = 70⁰

angle B = 70⁰

angle B = angle D = 70⁰(opposite angles)

So, angle A = angle C = 110⁰

angle B = angle D = 70⁰
