Learning how to reflect a polygon over the x=y line

The video tutorial explains how to reflect a geometric figure over the Y = X line. It begins by introducing the concept of reflection and the importance of swapping coordinates. The instructor then graphs the original triangle and explains the properties of the Y = X line. The process of reflecting the triangle by swapping the x and y coordinates is demonstrated, and the new points are labeled and plotted. The tutorial emphasizes the importance of labeling points for transformation and concludes with a visual representation of the reflected figure.

Why is it important to label points when reflecting them across the Y = X line?
