Transformations in the Coordinate Plane

This video tutorial covers transformations in the coordinate plane, focusing on translations and reflections. It explains how translations move objects left, right, up, or down, and how reflections flip objects over the x-axis or y-axis. The tutorial includes examples with points and shapes to illustrate these concepts.

What are the two types of transformations discussed in this video?

• Rotations and Translations

• Scaling and Shearing

• Translations and Reflections

• Rotations and Dilations
