Best ResponseYou've already chosen the best response.0how many edges do you count?

Best ResponseYou've already chosen the best response.0I'm counting 19 as well 5 edges in the outer circle 5 edges in the pentagon 8 curved edges on the inside (2*4 = 8) leading to the center 1 straight edge on the very inside leading to the center 5+5+8+1 = 19
