All

**regular polygons**and isotoxal**polygons**are**equilateral**. An**equilateral triangle is a regular triangle**with 60° internal angles. Thus if the number of sides n is odd, a tangential**polygon**is**equilateral**if and only if it is**regular**.

Likewise, is a regular Pentagon made up of equilateral triangles?

The requirement is that all angles must add **up** to 540 degrees and must be between 0 and 360 degrees but not equal to 180 degrees. In contrast, the **regular pentagon** is unique, because it is **equilateral** and moreover it is equiangular (its five angles are equal; the measure is 108 degrees).

**equilateral triangles**. In general,

**we can**split a regular

**polygon**with n sides into

**equilateral triangles**by using the

Similarly, is a equilateral triangle a regular polygon?

An **equilateral triangle** is a **regular polygon**. It has all the same sides and the same angles.

A circle is 360 degrees around Divide that by six angles So, the measure of the central angle of a regular **hexagon** is 60 degrees. A regular **hexagon** is **made** up of 6 **equilateral triangles**!
