# Is a quadrilateral a polygon?

Last Updated:

A quadrilateral is actually a polygon. In geometry, a polygon is a closed planar figure made up of line segments called sides.

For a shape to be considered a polygon, it must have at least three sides, whereas a quadrilateral has four.

Quadrilaterals are polygons with four sides, four vertices and four angles. They include various shapes, such as squares, rectangles, trapezoids and rhombuses.

Each of these shapes has specific properties, but they all share the fundamental characteristic of having four sides.

An interesting fact about quadrilaterals is that the sum of their interior angles is always 360°. Whether it’s a square with equal angles or a trapezoid with different angles, this rule remains.

The quadrilateral is one of the most frequent and essential polygons in geometry, enabling us to understand and solve various problems related to four-sided shapes.
