Formulas for Solid Geometry
Polygon Polygon is a closed plane figure made up of several line segments that are joined together. The sides do not cross each other. Exactly two sides meet at every vertex. Types of Polygons Regular – all angles are equal and all sides are the same length. Regular polygons are both equiangular and equilateral. Equiangular – all angles are equal. Equilateral – all sides are the same length.Polygon Formulas (N = number of sides , S = length from center to a corner)Area of regular polygon= (1/2) N sin(360°/N) S 2Sum of interior angles of a polygon = (N – 2) …
