Question

in a parallelogram ABCD the value of angle A + angle B is​

Answer 1

Answer:

the sum of 2 consecutive angles of a parallelogram gives a sum of 180.

Answer 2

Given,

The parallelogram ABCD is given.

To find,

We have to find the value of ∠A +∠B.

Solution,

The value of ∠A +∠B in a parallelogram ABCD is 180°.

We can simply find the value of ∠A +∠B in a parallelogram ABCD by using the properties of parallel lines, Parallelogram has 2 pairs of parallel sides.

In parallelogram ABCD, AB║CD and AD║BC.

AD║BC and AB is a transversal, then

∠A +∠B = 180° as the sum of co-interior angles is equal to 180°.

Hence, the value of ∠A +∠B in a parallelogram ABCD is 180°.
