Finding Midpoints and Endpoints

The video tutorial explains how to find the missing endpoint of a line segment when given one endpoint and the midpoint. It begins by plotting the given points and clarifying the problem setup. The concept of a midpoint is discussed, followed by the introduction of the midpoint formula. The tutorial then demonstrates how to apply the formula to solve for the missing endpoint by setting up and solving equations.
