How to reflect a figure over a line of symmetry ex 1

The video tutorial explains how to apply a reflection across a line, which serves as the line of symmetry. It emphasizes that reflection is a congruent transformation, meaning the size and shape of the figure remain unchanged. The tutorial demonstrates how to redraw the figure on the opposite side of the line, ensuring that distances from the line are equal on both sides. The process is illustrated with a rectangle, showing how to label the new figure as a prime. The tutorial concludes with a summary of the reflection process.
