In this lesson we are going to go over some special triangles. It is recommended to learn these problems and their properties because they can help you solve many math problems. The first triangle we are going to learn about is the 45-45-90 triangle. The hypotenuse of this triangle is sqrt(2) times as long as the leg. For example, if the leg is 2, the hypotenuse is 2 square roots of 2. The examples will help you understand this better. Another special right triangle is the 30-60-90 one. You will learn how the hypotenuse of this triangle is related to the legs. There are some tricky word problems that we are going to go over as well.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
