Who is Pythagoras, and why is he so important to geometry? Using a pithy discussion of altitudes and how to solve for the side lengths of right triangles—plus two proofs involving an altitude drawn in a right triangle—this program neatly sets the stage for the debut of the Pythagorean Theorem. An appraisal of the properties of the 45-45-90 and 30-60-90 triangles rounds out the program. (16 minutes)
