Properties of Quadrilaterals – Rectangle, Square, Parallelogram, Rhombus, Trapezium | 2023. In Euclidean geometry, a quadrilateral is a four-sided 2D figure whose sum of internal angles is 360°. The word quadrilateral is derived from two Latin words 'quadri' and 'latus' meaning four and side respectively.

A diamond is a two-dimensional flat quadrilateral with four closed straight sides. A diamond is also called a rhombus because it's sides are of equal measure and because the inside opposite angles are equal. Diamonds are also considered to be parallelograms because their opposite sides are parallel to each other.
