Exploring Rotations in the Coordinate Plane

The video tutorial covers rotations in the coordinate plane, focusing on three types: 90° counterclockwise, clockwise, and 180° rotations. It explains how to perform each rotation by changing the signs and positions of coordinates. The tutorial includes examples and practice exercises to reinforce understanding.

What is the result of rotating a point (x, y) 90 degrees counterclockwise around the origin?

• (y, -x)

• (-y, x)

• (x, -y)

• (-x, y)
