This video tutorial covers rotations on the coordinate plane, explaining how to rotate figures around a center of rotation to create congruent images. It discusses the degrees of rotation (90, 180, 270, 360) and the importance of direction (clockwise and counterclockwise). The tutorial includes examples and exercises to help understand the concept, and it highlights patterns in rotations, such as changes in coordinates. The lesson concludes with a summary of key points and encourages viewers to apply what they've learned.

What is the center of rotation typically used in coordinate plane rotations?

• The origin (0,0)

• The point (1,1)

• The top-left corner of the plane

• The center of the figure being rotated
