The sum of an interior angle and the exterior angle on the same vertex is always 180 ... gold chain vs silver chainWeb19 Feb 2024 · 1 Answer. Sorted by: 2. The key fact is that every simple polygon, not necessarily convex, can be decomposed into n − 2 triangles by drawing n − 3 diagonals. Then the sum of the interior angles of the polygon is equal to the sum of interior angles of all triangles, which is clearly ( n − 2) π. The existence of triangulations for simple ... gold chain valueWebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2. gold chain wallpaperWeb25 Sep 2024 · The Sum of interior angles of a polygon is always a constant value.
