Right Triangle Calculator


Home Page


This is a group of solvers that will solve for the unknowns in right triangles. Pick the image that has your two known parameters circled in red, insert your known quantities, and click calculate. All problems assume that one angle is 90 degrees. Remember that angles D and E will add up to 90 degrees. Subtract one from 90 to arrive at the other angle. Note, you can re-enter the numbers, or use another solver as many times as you wish without re-loading the page! Just click calculate again.
