WebAdjacent Vertices: The end-points of the same side of a polygon are adjacent vertices. Polygons are classified into Regular and Irregular Polygons. A Polygon in which all sides and all angles are equal is a regular polygon. The sum of all interior angles of a regular polygon = 180° × (n − 2), where n is the number of sides. WebA regular hexagon has 6 sides, so: Exterior Angle = 360 ° / 6 = 60° Interior Angle = 180 ° − 60° = 120° And now for some names: "Circumcircle, Incircle, Radius and Apothem ..." Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: WebGiven the number of sides of an object, and that each full rotation is 360 degrees, how could you determine each degree of rotation for any regular polygon? ...
