The formula for finding the amount of diagonals in a polygon is n(n-3)/2.
So 14(14-3)/2 = 77 Diagonals
Or Im not sure if this is it
So for n=8, we have 8*5/2=20.
I think it's 77 but Im not sure.

I thought he was talking about a 14 sided polygon so it would have 77. When you go on that website you just gave and make the polygon have 14 sides it says 77. But Im not sure. :/
