Polygons are many-sided figures, with sides that are line segments. Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. A regular polygon is one that has equal sides.
The word polygon is a combination of two Greek words: poly means many and gon means angle. Along with its angles, a polygon also has sides and vertices. Tri means three, so the simplest polygon is called the triangle, because it has three angles.It also has three sides and three vertices.A triangle is always coplanar, which is not true of many of the other polygons.ri means three, so the simplest polygon is called the triangle, because it has three angles.
