Reflecting a figure over a line of symmetry when it is on both sides

The video tutorial explains the process of reflecting points across a line to form a reflected figure. It emphasizes the importance of matching distances to accurately reflect points and suggests connecting the reflected points to complete the figure. The tutorial highlights the benefits of focusing on individual points rather than the entire figure for easier reflection.

What does the teacher imply about the importance of reflecting points?

Why might it be easier to reflect vertices instead of the whole figure?
