Reflection and Midpoints in Geometry

The video tutorial explains how to use the Reflection tool to map line segments by defining a line of reflection. It involves calculating midpoints between points on the original and reflected segments to determine the line of reflection. The process is demonstrated step-by-step, including plotting points and verifying the reflection. The tutorial concludes with a successful reflection, confirming the accuracy of the method.
