A concave polygon has one interior angle greater than 180°. A simple polygon encloses a single interior space (boundary) and does not have self-intersecting sides. Complex polygons have self-intersecting sides!
Polygon What is a Polygon? - Shape, Types, Formulas and …
WebPolygon Formulas (N = # of sides and S = length from center to a corner) Area of a regular polygon = (1/2) N sin(360°/N) S 2. Sum of the interior angles of a polygon = (N - 2) x 180°. The number of diagonals in a polygon = 1/2 N(N-3) The number of triangles (when you draw all the diagonals from one vertex) in a polygon = (N - 2). Polygon Parts WebEach interior angle of a regular dodecagon is equal to 150°. This can be calculated by using the formula: 180n–360 n 180 n – 360 n, where n = the number of sides of the polygon.
