![]() This makes it impossible to say that 45 45 90 triangles have the smallest hypotenuses. Since the value of a hypotenuse could be any rational, irrational, or real number, a 45 45 90 triangle could have the smallest hypotenuse of any triangle! However, the infinitesimal nature of these kinds of numbers makes a myriad of possibilities for the length of the hypotenuse of a 45 45 90 triangle. With the hypotenuse, we have information to determine the following: If you wanted to take a look at more examples of the 45 45 90 triangle, take a look at this interactive online reference for this special right triangle. You also happen to know a nice formula to figure out what the length of the hypotenuse is (the Pythagorean Theorem) and we'll show you how it will be used. Since you'll also find that this triangle is a right-angled triangle, we know that the third side that is not equal with the others is the hypotenuse. ![]() It is an isosceles triangle, with two equal sides. One of these triangles is the 45 45 90 triangle. For a list of all the different special triangles you will encounter in math. These are the ones you'll most typically use in math problems as well. But for the ones that do, you will have to memorize their angles' values in tests and exams. There's not a lot of angles that give clean and neat trigonometric values. Special triangles take those long numbers that require rounding and come up with exact ratio answers for them. When numbers are rounded, it means that your answer isn't exact, and that's something that mathematicians do not like. Most trig questions you've done up till now have required that you round answers in the end. Special triangles are a way to get exact values for trigonometric equations.
