Special Right Triangles
There are a few tricks you can use in certain right triangles to find out the lengths of all the sides if you only know the length of one side. The triangle either has to have two 45 degree angles, and a right angle; or it can have 30, 60, and 90 degree angles. In the 45, 45, 90 triangle; the hypotenuse is the length of one of the legs times the square root of two. in the 30, 60, 90; the long leg is the short leg times the square root of three, and the hypotenuse is twice the length of the short leg.
