Mastering Rotations on a Graph

This video tutorial demonstrates how to perform rotations on a graph, specifically focusing on rotating the letter R by various degrees without using coordinate rules. The instructor explains the process of visualizing rotations, including 90° clockwise, 90° counterclockwise, 180°, and 270° clockwise rotations. The tutorial emphasizes the ease of visualizing rotations by turning the paper instead of relying on coordinate transformations, making the process more intuitive and less cumbersome.

What is the primary method discussed for visualizing rotations in the video?

• Using coordinate rules

• Calculating angles algebraically

• Visualizing without coordinates

• Using a protractor
