Transformations and Reflections in Geometry

The video introduces transformations on the coordinate plane, focusing on reflections. It explains different types of transformations, such as dilation, rotation, and translation, and details the concept of reflections, including prime notation. The video demonstrates how to perform reflections using coordinates and provides shortcuts for reflecting over common lines like the x-axis, y-axis, and y=x.
