Likewise, people ask, is a polygon a quadrilateral?

**Polygons** - **Quadrilaterals** - First Glance.A**quadrilateral** is a four-sided **polygon** withfourangles. There are many kinds of **quadrilaterals**. Thefivemost common types are the parallelogram, the rectangle, thesquare,the trapezoid, and the rhombus.
