WebSep 7, 2024 · A diagonal can go to any vertex except the one it starts at and the two neighbors, so there are 39 destinations for each of the 42 starting points. This gives a total of “directed diagonals”; dividing by 2, we have 819 diagonals. We didn’t need an actual formula after all, did we?
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. John Conway labels these symmetries … WebHow many diagonals does a regular n-gon have?----The n-gon will have n vertices.---Every pair of vertices determines a line segment. You have nC2 = n(n-1)/2 pairs of vertices. So you have n(n-1)/2 line segments determined.-----n of those line segments are sides of the n-gon.-----So the number of diagonals is [n(n-1)/2] - n
