How to find the legs of a special right triangle when given the hypotenuse

The video tutorial explains the properties of special right triangles, focusing on the relationship between the legs and the hypotenuse. It describes how to calculate the hypotenuse by multiplying the leg by the square root of 2 and how to find the legs if the hypotenuse is given by dividing by the square root of 2.

What value do you divide by to go backwards from the hypotenuse to find the legs?
