Yes, I mean connecting the verticies.

If you mean by connecting the vertacies, just break out a pencil and paper and do it.
If you mean just how many diagonal lines, it's infinate.

From each vertex, you'll be able to draw one diagonal line for each other vertex after 3 (so with an octogon, you'll be able to draw 5 lines from each point). But that's only for the first and second vertices (because those two vertices are not connected by previously drawn lines). After that, each vertex will have one less available line than the one before it. So the sum of all the lines will be:
5 + 5 + 4 + 3 + 2 + 1 + 0 + 0 = 20

An octogon has 8 sides, so you can draw 4 lines.
