Question

The adjacent angal of parallelogram are _answer


​

Answer 1

Answer:

The adjacent angle of a parallelogram are supplementary angle , or add up to be 180° .

Answer 2

Let ABCD be a parallelogram

Problems on Parallelogram
Then, AD ∥ BC and AB is a transversal.

Therefore, A + B = 180° [Since, sum of the interior angles on the same side of the transversal is 180°]

Similarly, ∠B + ∠C = 180°, ∠C + ∠D = 180° and ∠D + ∠A = 180°.

Thus, the sum of any two adjacent angles of a parallelogram is 180°.

Hence, any two adjacent angles of a parallelogram are supplementary.
