WebJan 26, 2024 · All heptagons will have 14 diagonals; if a diagonal lies outside the polygon, you know the heptagon is concave. No, heptagons only have seven sides. A 9 sided polygon is called a nonagon. Of the eight figures, only five are heptagons. Two are regular convex heptagons. Three are irregular concave heptagons.

WebSep 7, 2024 · So there should be 3*6 = 18 diagonals, but in fact if you count them there are only half as many. Why? Well, since a single diagonal joins exactly two vertices, for each vertex we counted the same diagonal twice . Each diagonal is the starting point for 3 “directed diagonals”: Two of these correspond to one actual diagonal. So look at a 42-gon.
