bezier curves

Bezier curves are used to draw curved lines on a computer. They are kind of like a roller coaster, except on a computer screen! A Bezier curve starts and ends in two different places, and can have one or more curves in between. To create a Bezier curve, you need two things: points and handles. Points are like the beginning and end of a roller coaster track. Handles are like the support beams that help hold the track up. By moving the handles and points, you can change the shape of the curve.
