Question

Consecutive Angles of a parallelogram are

• A. Equal
• B. Supplementary
• C. Complementary
• D. None of these

Answer 1

The correct option is B

Supplementary

Explanation for correct option:

A parallelogram ABCD is given.

AB$\parallel$CD and AD is the transversal.

We know that the interior angles on the same side of the transversal are supplementary.

$\Rightarrow \angle \mathrm{A}+\angle \mathrm{D}=180°$

Similarly$$\begin{gathered} \angle B+\angle C=180°, \\ \angle C+\angle D=180°,\angle A+\angle B=180° \end{gathered}$$

$\therefore$Consecutive Angles of a parallelogram are supplementary.

Hence, Option (B) is the correct option.
