Parallelogram Diagonals: Properties And Intersection Point

Diagonals are line segments connecting opposite vertices of a parallelogram. They intersect at a single point, which is the midpoint of both diagonals. This point divides each diagonal into two congruent segments, making the diagonals bisect each other. Parallelograms have two pairs of parallel sides, and their diagonals bisect each other.
