Question

In a parallelogram ABCD, if ∠A = 60°, then what is the measure of ∠D ?​

Answer 1

Answer:

D is equal to 60° because all the angles are equal in a parallelogram

Answer 2

Given:-

• ∠A of parallelogram ABCD is 60°.

To find:-

• ∠D of parallelogram.

SolutiOn:-

We know that,

Sum of adjacent angles of parallelogram is 180°.

So,

∠A + ∠D = 180°

60° + ∠D = 180°

∠D = 180° - 60°

∠D = 120°

Therefore,

∠D of parallelogram ABCD is 120°.
