Named after the French mathematician Pierre Bézier, Bézier curves employ at least three points to define a curve. The two endpoints of the curve are called *anchor points*. The other points, which define the shape of the curve, are called *handles*, *tangent points*, or *nodes*. Attached to each handle are two *control points.*By moving the handles themselves, or the control points, you can modify the shape of the curve.
