Question

Which of the following is not true for a Parallelogram?

• A. opposite sides are equal
• B. opposite angles are equal
• C. opposite angles are bisected by the diagonals
• D. diagonals bisect each other.

Answer 1

The correct option is C

opposite angles are bisected by the diagonals

Explanation.

The four most important properties of a parallelogram are:

• The opposite sides of a parallelogram are equal in measurement and they are parallel to each other.
• The opposite angles of a parallelogram are equal.
• The sum of interior angles of a parallelogram is equal to $360°$.
• The consecutive angles of a parallelogram should be supplementary $(180°)$.

Thus, opposite angles are bisected by the diagonals is not a property of parallelogram.

Hence, option $\mathrm{C}$ is correct.
