Regular Polygons Information

Regular and Irregular Polygons

Here is a list of regular polygons from 3 to 10 sides.

For each polygon, a regular and an irregular example have been shown.

Any regular polygon will be mathematically similar to the example shown (having the same angles).

There are an infinite number of examples of different irregular polygons that could be shown, and only one example is given.

 Equilateral Triangle Angle: 60° Interior angles add up to 180° Irregular Triangle Square Angle: 90° Interior angles add up to 360° Irregular Quadrilateral Pentagon Angle: 108° Interior angles add up to 540° Irregular Pentagon Hexagon Angle: 120° Interior angles add up to 720° Irregular Hexagon Heptagon Angle: 128.6° Interior angles add up to 900° Irregular Heptagon Octagon Angle: 135° Interior angles add up to 1080° Irregular Octagon Nonagon Angle: 140° Interior angles add up to 1260° Irregular Nonagon Decagon Angle: 144° Interior angles add up to 1440° Irregular Decagon

The formulae for the interior angles of a polygon are as follows:

Total of interior angles = 180 x (number of sides - 2)

Angle = total of interior angles / number of sides
