Are regular polygons made up of equilateral triangles?
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).
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!
