Using the Pythagorean theory, a number of problems were worked on which involved finding a leg or hypotenuse of a triangle. A more difficult problem was presented in which the right triangle had to be constructed from other information before the problem could be solved. Some special right triangles were introduced, along with terms like similar, equilateral, and congruent. Examples of each was presented along with the line, triangle, and angle methods of designation. A method of solving a 30-60-90 triangle by using a formula derived from the pythagorean theory was presented and solved
