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

A parallelogram is a quadrilateral in which a pair of opposite sides are equal and parallel. Because of this, its diagonal always bisect each other and opposite angles are also equal.

Hence, options (a),(b) and (d) are true.

But a diagonal may or may not bisect the opposite angles of a parallelogram and hence this cannot be considered as a fact.

Therefore, option (c) is not true.
