You'll help her by writing a simple computer program-a set of instructions for the computer. She doesn't even know how to draw shapes, like a triangle, yet. The kitty is a cartoon character who is just a beginning artist.

In this computer science project, you are going to teach a kitty how to draw. Then you have to turn 120 degrees again, so that you can come back to Point A. To draw a triangle, you start at Point A, travel to Point B, and then have to turn very far-120 degrees-so that you can continue on the path to Point C. Now suppose your friend tells you that she wants to learn how to draw a triangle, so you show her that path, too.
