| − | ==45-45-90 Special Right Triangles==
| + | #REDIRECT [[Special right triangles]] |
| − | | |
| − | This concept can be used with any [[right triangle]] that has two <math>45^\circ</math> angles.
| |
| − | | |
| − | A 45-45-90 Triangle is always [[isosceles]], so let's call both legs of the triangle <math>x</math>.
| |
| − | | |
| − | If that is the case, then the [[hypotenuse]] will always be <math>x\sqrt 2</math>.

| − | ==30-60-90 Special Right Triangles==
| |
| − | | |
| − | 30-60-90 Triangles are special triangles where there is a certain ratio for the sides of the right triangle, as explained below.
| |
| − | | |
| − | This concept can be used for any right triangle that has a <math>30^\circ</math> angle and a <math>60^\circ</math> angle.
| |
| − | | |
| − | Let's call the side opposite of the <math>30^\circ</math> angle <math>x</math>.
| |
| − | | |
| − | Then, the side opposite of the <math>60^\circ</math> angle would have a length of <math>x\sqrt 3</math>.
| |
| − | | |
| − | Finally, the hypotenuse of a 30-60-90 Triangle would have a length of <math>2x</math>.
| |
| − | | |
| − | There is also the ratio of 1:sqrt(3):2. With 2 as the hypotenuse and 1 opposite of the <math>30^\cic</math>. That leaves sqrt(3) as the only length left.
