Please have a look at this website. It has animations that will walk you through several different geometric constructions that are very handy in design and layout. Remember that a compass and straight edge are far more accurate than trying to transfer several dimensions. http://www.mathopenref.com/constangle90.html
Thanks guys. I’ve posted about this book before but here it is again. This book changed the way that I look at everything, especially how I design my woodworking projects.

Here’s a link for a triangle calculator that I find helpful if you’re trigonometrically challenged like me. http://ostermiller.org/calc/triangle.html
