Ans. Bimedian of a quadrilateral is a line segment that connects the midpoints of the opposite sides in a quadrilateral. The intersection point here is known as the centroid of vertices of the quadrilateral. Moreover, the bimedians of a quadrilateral and the segment, which connects these two midpoints of a diagonal are concurrent, and the point of intersection bisects them. Additionally, in a convex quadrilateral, there is a dual connection between these bimedians and diagonals. Hence, bimedians with equal length suggest that two diagonals are perpendicular, and if diagonals have equal length, then these bimedians will be perpendicular.
