How to determine the sides of a triangle by using the geometric mean

The video tutorial explains how to represent a side of a triangle, specifically focusing on the hypotenuse and its relationship with the short and long legs. It covers the use of geometric mean to find the lengths of sides A and X, and demonstrates the application of cross multiplication in solving these geometric problems. The tutorial emphasizes understanding the relationships between different sides of a triangle and how to calculate them using geometric principles.

In the context of the big triangle, how do you determine which side is the long leg?

Explain the process of cross multiplication as it relates to finding 'b' in the triangle.
