In a parallelogram ABCD, if angle A=30 degree find the measure of the Other angles

Answer»

In a Parallelogram the ADJACENT angles are supplementary and the opposite angles are equal.


So Adjacent angles of A are : ∠ B and ∠ D


HENCE ∠ A + ∠ B = 180°


=> 30° + ∠ B = 180°


=> ∠ B = 180° - 30° = 150°


We know that ∠ A = ∠ C and ∠ B = ∠ D as they are opposite angles. Hence,


∠ A = ∠ C = 30°


∠ B = ∠ D = 150°
