The full name of a 13-sided polygon is a triskaidecagon. However, with polygons of such size, it's common practice to call them n-gons, so in this case the shape would be called a 13-gon.
A 13 sided shape is a tridecagon or tristedecagon. The roots to this word are tri (meaning 3) and dec (meaning ten). 3 + 10 = 13.
