Reflections: The Mathematical Flip

The video lesson covers reflections, a type of transformation where figures are flipped over a line of reflection, maintaining congruence. It explains key vocabulary, provides real-world examples, and guides viewers through identifying reflections and performing them in the coordinate plane. The lesson includes exercises to practice reflecting figures over the x and y-axes, emphasizing the importance of congruence and the rules governing reflections.
