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°.
