How many diagonals are there in a convex polygon?

Since for an n-sided convex polygon, from each vertex, we can draw n-3 diagonals leaving two adjacent vertices and itself. Following this way for n-vertices, there will be n* (n-3) diagonals but then we will be calculating each diagonal twice so total number of diagonals become n* (n-3)/2

How many sides does a 13 sided tridecagon have?

In geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

Which is a 13 sided polygon in geometry?

In geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon

Are there any dihedral symmetry in the tridecagon?

Since 13 is a prime number there is one subgroup with dihedral symmetry: Dih 1, and 2 cyclic group symmetries: Z 13, and Z 1 . These 4 symmetries can be seen in 4 distinct symmetries on the tridecagon. John Conway labels these by a letter and group order. Full symmetry of the regular form is r26 and no symmetry is labeled a1.
