First let me say that if this is too simple for this site I am sorry. I'm just a old timer that is trying to maximize my cuts on a sheet of plywood. Trapezoid Question I know the base measurement and the angles of the trapezoid. I need the sides and the top to be equal Is there a formula that I can input the base length and angles to find the 3 equal sides? The reverse to this question I know the equal length of the 2 sides and the top. I know the degrees of the angles Is there a formula that will tell what the base needs to be. Thanks for your help -- Tony Welscher
