These two pages are notes for finding missing sides of a right triangle using the Pythagorean theorem. The first page is for finding the hypotenuse, 'c', and the second page is for finding a missing leg, 'a' or 'b'. I provide one example problem for both kinds of problems with three practice problems for each type of Pythagorean problem. Two of the problems are word problems, one for each type of Pythagorean problem.
