Learn how to reflect a figure over a line of symmetry

The video tutorial explains how to reflect an image over a line of symmetry. It emphasizes that the size and shape of the reflected image remain unchanged from the pre-image. The line of symmetry is likened to a hinge, and the importance of maintaining equal distances from the pre-image to the line of symmetry is highlighted. An example is provided to illustrate the reflection process, showing how the image and its reflection maintain consistent distances.

Describe the process of reflecting a figure over a line of symmetry as explained by the teacher.

What does the teacher mean by calling the reflected image 'A prime'?
