How many diagonals does a 42-gon have

WebApr 8, 2024 · For n = 4 we have quadrilateral . It has 2 diagonals. Therefore, the number of diagonals in a polygon quadrilateral is 2. For n = 5, we have a pentagon with 5 diagonals. … WebThe number of diagonals of a polygon is calculated by: n (n−3) ÷ 2. In decagon, n is the number of sides which is equal to 10, so n=10. Now we get, n (n−3) ÷ 2 = 10 (10−3) ÷ 2 Thus, the number of diagonals in a decagon is 35. Decagon has 8 Triangles By joining one vertex to the remaining vertices of the decagon, 8 triangles will be formed.

WebA regular triangle, heptagon, and 42-gon can completely fill a plane vertex. However, there is no tiling of the plane with only these polygons, because there is no way to fit one of them onto the third side of the triangle without leaving a gap or creating an overlap. In the hyperbolic plane, tilings by regular heptagons are possible. WebBut with every other end point, there’s a diagonal, shared by the two end points. Hence for each endpoint it owns ( N-3)/2 diagonal to itself. So for N endpoints there are N (N-3)/2 …
