Question

If ABCD is a parallelogram, what can we say about the diagonals BD and AC? 

Answer 1

A parallelogram is a quadrilateral with two pair of parallel sides. The opposite sides of parallelogram are in equal length and opposite angles are of equal measure.

ABCD is a parallelogram with sides as AB, BC, CD and AD. BD and AC are the diagonals of the given parallelogram.

In parallelogram opposite sides are equal that is AB=CD, AD=BC

opposite angles are equal $\angle A = \angle C$ , $\angle B = \angle D$

Diagonals of parallelogram bisect each other.

Diagonals of parallelogram BD and AC are not congruent to the sides AB , CD and AD , BC.

Diagonals are not congruent.

Diagonals always bisect each other.

Option C is correct.
