Question

in a parallelogram ABCD measure of angle A is three times the measure of Angle B find all the four angles​

Answer 1

Answer:

Let the angle A be 3x

the angle B be x

3x + x = 180° ( co-intr angles )

4x = 180°

x = 180°/4

x = 45°

Therefore , Angle A = 3x = 3 × 45° = 135°

Angle B = x = 45°

Angle A = Angle C = 135° ( opp. angles of parallelogram are equal)

Angle B = Angle D = 45° ( reason as above )
