WebWe will learn how to find the number of triangles contained in a polygon. If the polygon has ‘n’ sides, then the number of triangle in a polygon is (n – 2). In a triangle there are three sides. In the adjoining figure of a triangle ABC we can observe that the number of triangles contained = 3 – 2 = 1. In a quadrilateral there are four ... Web3 nov. 2024 · The above interior angle formula is derived by dividing a polygon into triangles, and this number can be found with the calculation: n - 2. In this formula, n is equal to the number of sides of the polygon. A hexagon (six sides) can be divided into four triangles (6 - 2) and a dodecagon into 10 triangles (12 - 2).
Web7 apr. 2024 · A pentagon is a two-dimensional shape with 5 sides and 5 angles in geometry. An angle is produced in a pentagon when two of its sides share a common point. Because there are five vertices in a pentagon, there are five angles in a pentagon.
