Which of the following properties is always true for a parallelogram?

Question

Diagonals bisect each other.

Diagonals are perpendicular.

Diagonals are congruent.

Diagonals bisect opposite angles.

Answer 1

The property that is always true for a parallelogram is:

Diagonals bisect each other.

In a parallelogram, the two diagonals intersect at a point that divides each diagonal into two equal parts. The other properties listed (diagonals being perpendicular, diagonals being congruent, and diagonals bisecting opposite angles) are not true for all parallelograms; they may hold for specific types of parallelograms like rectangles and rhombuses, but not for parallelograms in general.
