How to Find Regular Polygon Sides from Exterior Angle
Показать описание
Determining the number of sides in a regular polygon when given that an exterior angle measures 72 degrees.
Regular polygons have the property that the sum of all exterior angles equals 360 degrees. By applying this information, we can calculate the number of sides in a regular polygon by dividing 360 degrees by the measure of an exterior angle.
