It comes up when installing diagonal support pieces on a picnic table, picnic bench, or any project with diagonal support pieces. In this case, I am running diagonal supports between two horizontal surfaces. The cuts are on opposite sides of the support piece, meaning the angle cut is on the top of the high end of the support and on the bottom side of the low end of the support. I can’t just lay the diagonal piece against the horizontal pieces and make a pencil mark to show the angle. My angle cuts never seem to be right on the money, as I’m always just guessing. Can any of you guys give me a simple method to figure this out? I know the Pythagorean theorem will tell me the length of the support piece, but how do I find the angle? I believe that the two angles should be the same because they are corresponding angles, but it’s been a long time since math class. Please help, this is bugging the heck out of me. Any youtube videos would be great. Thanks,John -- John - Huntington Beach, CA --- Growth occurs when we get out of our comfort zone.
