Hlo mate here is ur ans....

Here. ABCD is a parallelogram.

Here. ABCD is a parallelogram.The, AD∥BC and DC is a transversal.

Sum of the interior angles on the same side of the transversal is 180° .

.∴ ∠C+∠D=180°

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

==> The sum of ∠C and ∠D is 180°
