How to use the triangle midsegment formula to find the midsegment

The video tutorial explains how to solve a geometry problem involving the mid segment of a triangle. It introduces the problem, discusses the properties of mid segments such as congruency and parallelism, and presents the formula for calculating the mid segment. The solution is demonstrated by applying the formula to find the length of the mid segment JH, which is half the length of the base KM, resulting in a value of 11.
