Exploring Rotations in Geometry

This video tutorial covers the concept of rotations in geometry, focusing on rotating shapes clockwise and counterclockwise around a fixed point, typically the origin on a Cartesian plane. It explains the use of the prime symbol for labeling rotated objects and provides step-by-step examples of rotating points and complex shapes. The tutorial also introduces advanced techniques for ensuring shapes remain equidistant from the origin during rotation.

What direction does a clockwise rotation move?

• None of the above

• In a straight line

• In the same direction as an analog clock

• Opposite to an analog clock
