Midpoint and Circle Geometry Problems

The video tutorial explains how to solve problems using the midpoint formula. It begins with an introduction to the formula, followed by a detailed example of finding a missing endpoint of a line segment when given one endpoint and the midpoint. The tutorial then applies the same method to find the other endpoint of a circle's diameter, demonstrating the formula's versatility in different geometric contexts.
