Parallelogram with 90 Degree Angle

This image displays a parallelogram with its two diagonals drawn, meeting at a central point. A notable feature is the blue arc indicating a 90-degree angle at their intersection, clearly showing that the diagonals are perpendicular. This specific geometric property is characteristic of a rhombus, which is a special type of parallelogram.
