In this lesson I will teach you about special right triangles. We will focus on two special right triangles- the 45-45-90 degree special right triangle and the 30-60-90 degree special right triangle. I will be teaching you formulas that we can use to find the lengths of the sides of these special right triangles. These formulas are extremely important for you to learn. If you plan on going to college you will have to take the SAT or ACT test. I mention this because special right triangle problems are very common on these and other tests- trust me you need to master the skills in this lesson. Basically the formulas for special right triangles are ratios of the lengths of the sides of the triangle. Once you understand how the formulas work it’s very easy to find the measure of all the sides of a special right triangle. Also because we are talking about right triangles you can use the Pythagorean Theorem as well to solve problems. Remember to take great notes and I can’t stress how important it is for you to practice this topic. Good luck!
