Are you looking for an answer to the topic “What is the exterior angle of a regular decagon?“? We answer all your questions at the website Ecurrencythailand.com in category: +15 Marketing Blog Post Ideas And Topics For You. You will find the answer right below.
In the regular decagon, all angles are equal. The sum of all exterior angles of the regular decagon is 360°. As the number of sides is 10 in a decagon. Therefore each exterior angle is equal to 36°(360° ÷ 10 =36°).Simply divide 360 by the number of sides of the polygon. 360/10=36° is the measure of each exterior angle of the regular polygon.Decagon Angles
