Reflecting a polygon over a horizontal line of symmetry

The video tutorial explains how to reflect a polygon across a symmetrical line, referred to as line M. It emphasizes maintaining equal distances from the line for accurate reflection. The tutorial covers plotting new points, handling points directly on the line, and the importance of correct labeling of transformed points. The instructor provides a step-by-step guide to ensure the reflection is accurate and properly labeled.

How do the points Y and Z behave when reflected over the line M?

Why is it important to relabel the transformed points such as Y prime and W prime?
