Study Notes

Regular Polygons

All sides are equal in length
All interior angles are equal in measure

Irregular Polygons

Sides are not all equal in length
Interior angles are not all equal in measure

Measuring Angles in Polygons

The sum of the interior angles of a polygon with n sides is (n - 2) * 180 degrees
To find the measure of each interior angle of a regular polygon, divide the sum of the interior angles by the number of sides

Hexagon

A hexagon is a polygon with 6 sides

Decagon

A decagon has 10 sides
The sum of the interior angles of a decagon is (10 - 2) * 180 = 1440 degrees
Each interior angle of a regular decagon measures 1440 / 10 = 144 degrees
