Learn how to rotate a triangle 90 degrees clockwise about the origin

The video tutorial explains how to rotate a figure 90 degrees clockwise using both manual and algebraic methods. It begins with a manual approach using paper to visualize the rotation, followed by an algebraic method that involves swapping and negating coordinates. The tutorial also covers plotting the new coordinates and compares clockwise and counterclockwise rotations.
