How to determine the legs of a 45 45 90 triangle when given the hypotenuse

The video tutorial explains the properties of a 45-45-90 triangle, focusing on how to find the hypotenuse by multiplying the leg by the square root of 2. It then addresses the reverse process of finding the leg from the hypotenuse by dividing by the square root of 2. The tutorial concludes with a discussion on rationalizing the denominator by multiplying both the numerator and denominator by the square root of 2 to eliminate the square root from the denominator.
