The video tutorial explains how to find the other endpoint of a line segment when one endpoint and the midpoint are known. The instructor introduces the problem, provides a method to solve it, and walks through the step-by-step calculation. The key idea is to use the change in coordinates from the known endpoint to the midpoint to determine the change to the other endpoint.
