The triangle on the left has the square labels a squared equals 16 aligned to the bottom horizontal leg and b squared equals 10 aligned to the left leg. Students use similarity to prove the Pythagorean theorem and the converse of the Pythagorean theorem. A right triangle A B C where angle A C B is the right angle. In Topic B, Right Triangle Trigonometry, and Topic C, Applications of Right Triangle Trigonometry, students define trigonometric ratios and make connections to the Pythagorean theorem.
