Answer 2

Given,

ABCD is a parallelogram.

One angle of parallelogram ∡ A = 70°

To Find,

Parallelogram's remaining angles.

Solution,

Here, ABCD is a parallelogram.

The angle A = 70°.

Parallegorm has equal opposite sides.

4 interior angles are in a parallelogram, and all the angles total is 360°.

Adjoining angles total is 180°.

Therefore,

∡ A =70 °

∡A and ∡B are close by angles.

∡A + ∡B = 180°

∡ B = 180-70

∡B = 110°

One characteristic of a parallelogram is its opposite sides are the same.

Here,

∡C and ∡A, ∡B, and ∡D are opposite to each other.

∡A= ∡C

∡B = ∡D

Hence ∡A = 70°, ∡C = 70°, ∡B = 110°, ∡D = 110°.
