Then we will use the Pythagorean theorem to find the remaining side length.Ī: The 3-4-5 triangle rule uses this well known pythagorean triple.

Q: How to do multi-step special right triangles?Ī: If we are given a right triangle with one acute angle and side length known, we will first utilize our special right triangle ratios to find one missing side length (either a leg or hypotenuse). We can find the hypotenuse by using the Pythagorean theorem or trigonometric ratios by fist ordering side lengths in increasing value, as seen in the video. Q: How to find the hypotenuse in special right triangles?Ī: The hypotenuse is always the longest side of a right triangle. Additionally, you will discover why it’s very important on how you choose your side lengths. In the video below, you will also explore the 30-60-90 triangle ratios and use them to solve triangles. Solve the right triangle for the missing side length and hypotenuse, using 45-45-90 special right triangle ratios. Consequently, knowing these ratios will help us to arrive at our answer quickly, but will also be vital in many circumstances. The Pythagorean theorem requires us to know two-side lengths therefore, we can’t always rely on it to solve a right triangle for missing sides. Rather than always having to rely on the Pythagorean theorem, we can use a particular ratio and save time with our calculations as Online Math Learning nicely states.Īdditionally, there are times when we are only given one side length, and we are asked to find the other two sides. Well, one of the greatest assets to knowing the special right triangle ratios is that it provides us with an alternative to our calculations when finding missing side lengths of a right triangle. Moreover, we will discover that no matter the size of our special right triangle, these ratios will always work.īut why do we need them if we have the Pythagorean theorem for finding side lengths of a right triangle? Together we will look at how easy it is to use these ratios to find missing side lengths, no matter if we are given a leg or hypotenuse.
