When we add up the Interior Angle and Exterior Angle we get a straight line 180°, so they are "Supplementary Angles".PolygonsA Polygon is any flat shape with straight sidesThe Exterior Angles of a Polygon add up to 360°In other words the exterior angles add up to one full revolution....
The angles of a polygon are the angles between the sides. A regular polygon has equal angles and the sum of the internal angles is given by the formula 180(n-2), where n is the number of sides of the polygon. For example, the sum of the internal angles of a triangle is 180°, ...
