# Rotations: Introduction

- Author:

The applet below was designed to help you better understand what it means to rotate a point about another point.
In the applet below, feel free to change the locations of point

*A*and point*B*. Interact with this applet for a few minutes, then answer the questions that follow.**Questions:**1) Regardless of the

**amount of rotation**, how does the distance

*AC*compare to the distance

*AB*? 2) Notice how, in the applet above, the

**angle of rotation**could be

**positive**or

**negative**. From what you've observed, what does it mean for a

**rotation angle**to have positive orientation? What does it mean for an

**angle of rotation**to have negative orientation? Explain.
