Question

1. In the adjoining figure, ABCD is a parallelogram in which angle A=50°. Find the measure of each of the remaining angles of the parallelogram.
​

Answer 1

Angle A = 50°

Angle C = 50° (Opposite angles r equal in a parallelogram)

Angle B = 180-50

= 130°

Angle D = 130° (Opposite angles r equal in a parallelogram)

Answer 2

Answer:

If smallest angle is A, then the reqd angles are A, 180-A, A, 180-A

Here 2A - (180-A) = 15 => 3A = 195 => A = 65

So the angles are 65, 115, 65, 115
