Reflecting a triangle over a line of symmetry

The video tutorial explains how to reflect points over a line in geometry. It emphasizes the importance of considering each point individually and reflecting it across a line to maintain equal distances. The tutorial suggests connecting the reflected points to form a complete figure, simplifying the process by focusing on individual points rather than the entire shape. The instructor provides practical tips to make the task less confusing and more engaging.
