How to solve a regular polygon
WebUsing our polygon formula, (12 – 2) * 180 = 1800°. Isn't that amazing? Individual Angles This formula can be used to find individual angles if the polygon is regular. For a regular octagon, such as a stop sign, the sum of all eight angles is 1080°, so each angle must be 1080/8 = 135°. Each angle in a regular hexagon is (6 – 2) * 180 / 6 = 120°. WebMeasure of any angle in a regular n-gon = For an n-gon with sides of length x, the perimeter is simply nx (since the figure has n sides of length x). Calculating the area of a regular n …

WebSo if we want to figure out the perimeter here, it'll just be x plus x plus x plus x, or 4x. Let me write that. x plus x plus x plus x, which is equal to 4x, which is going to be equal to 36. They gave us that in the problem. And to solve this, 4 times something is 36, you could solve that probably in your head. WebImagine a regular pentagon, all sides and angles equal. Orient it so that the bottom side is horizontal. Now remove the bottom side and slide it straight down a little bit. Extend the sides you separated it from until they touch the bottom side again. They'll touch it somewhere in the middle, so cut off the excess.
