You'll get a detailed solution from a subject matter expert that … WebA diagonal line is a line segment that connects the two vertices of a shape, which are not already joined by an edge. It does not go straight up, down or across. The shape of the diagonals is always a straight line. In other words, a diagonal is a straight line that connects the opposite corners of a polygon or a polyhedron, through its vertex.

WebThe regular pentadecagon has Dih 15 dihedral symmetry, order 30, represented by 15 lines of reflection. Dih 15 has 3 dihedral subgroups: Dih 5, Dih 3, and Dih 1. And four more cyclic symmetries: Z 15, Z 5, Z 3, and Z 1, with Z n representing π/ n radian rotational symmetry. On the pentadecagon, there are 8 distinct symmetries. WebA polygon of n sides has n (n-3)/2 diagonals. Here n = 15, hence the number of diagonals the 15-gon has = 15*12/2 = 90. 687 views View upvotes 1 Chris Manning B. Math.

WebRegular Polygon case In the case of regular polygons, the formula for the number of triangles in a polygon is: where n is the number of sides (or vertices) . Why? The triangles are created by drawing the diagonals from one vertex to all the others.
