Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons. Now we will begin to look at some . POLYGONS HAVING INTERIOR ANGLE WITH NO DECIMAL VALUES 1. This is because any simple n -gon ( having n sides ) can be considered to be made up of ( n − 2) triangles, each of which has an angle sum of π radians or 180 degrees. The sum of the interior angles of an n-sided polygon always is 90 x (2n - … The area of a regular pentacontagon is (with t = edge length) There are two basic types of polygons, a convex and a concave polygon. 150 degrees To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)… And there are twelve angles… So, the measure of the interior angle of a regular dodecagon is 150 degrees. 100. = 180 ° (n − 2) S. I. The triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons: 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°). A polygon is a closed two- dimensional shape. Hence in a polygon with n sides (or angles), the sum of all the interior and exterior angles would be 180∘ ×n. Polygon is a closed plane figure bounded by straight lines. Hectogon, Hecatontagon. Convex, cyclic, equilateral, isogonal, isotoxal. The sum of the interior angles of a polygon is 1,440. The original argument requires students to make use the angle measure of a straight angle, and about alternate interior angles formed by a transversal cutting a pair of parallel lines (material developed experimentally via transformational geometry, e.g., in pursuing 8.G.1.b). Myriagon.
