Interior angle and each exterior angle of a regular 18-gon?

Interior angle measure of a 18-gon = [180⁰(18 - 2)]/18 = 10⁰(16) = 160⁰. Exterior angle measure = 180⁰ - 160⁰ = 20⁰.

Measures of an exterior angle of 20-gon?

Well, honey, an exterior angle of a polygon can be found by dividing 360 degrees by the number of sides. So for a 20-gon, each exterior angle would be 18 degrees. It's as simple as that, darling.

Interior angle and each exterior angle of a regular 18-gon?

Interior angle measure of a 18-gon = [180⁰(18 - 2)]/18 = 10⁰(16) = 160⁰. Exterior angle measure = 180⁰ - 160⁰ = 20⁰.

What is the measures of one exterior angle of a regular 18-gon?

The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be: 360° 18 = 20°Therefore the measure of one exterior angle of a regular 18-gon is 20°.
