The sum of angles in a polygon depends on the number of edges and vertices of a polygon. The sum of the angles in a polygon is calculated for two types of angles of a polygon which are Interior angle and Exterior Angle.

Futility Closet recently posted a nice puzzle about the sum of the angles in the “points” of a star polygon. It’s easy to show that the five acute angles in the points of a regular star, like the one at left, total 180°. ...
Simple Polygon –A simple polygon has only one boundary. The sides of a simple polygon do not intersect. Complex Polygon –Complex polygon is a polygon whose sides cross over each other one or more times. Sum of Angles of a Polygon
A polygon has 9 sides. The sum of its interior angles is: A. 1260 degrees B. 1440 degrees C. 1620 degrees D. 1800 degrees 相关知识点: 试题来源: 解析 A。根据公式 (n - 2) × 180,边数 n = 9,内角和为 (9 - 2) × 180 = 1260 度。
Sum of Interior Angles of a Polygon Main Concept An interior angle is an angle located inside a shape. For example, a triangle has three interior angles, with a sum of 180. As the number of sides, n , of a polygon increases, the sum of its interior angle
The sum of interior angles in the top left diagram of a dissected polygon is (1) But (2) and the sum of angles of the triangles is (3) Therefore, (4) The same equation can be derived using exterior angles (top right figure) or a triangulation from a single vertex (bott...
The Interior Angles of a Pentagon add up to 540°The General RuleEach time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total:If it is a Regular Polygon (all sides are equal, all angles are equal) ShapeSidesSum of Interior ...

If the polygon is not regular (the sides or angles are not all equal), it is much more difficult and often impossible to calculate the degrees of the individual interior angles, however, you can calculate the sum of the interior and exterior angles the same way you would with a regular ...
