Move the
LARGE POINT P to various locations around the circle. Each time you do,
- Press the Make Segment button.
- Drag the segment you just made so its endpoint that originally touched the horizontal axis now touches the open-holed point on the right. (See quick screencast below.)
- Repeat steps (1) - (2) numerous times. Get as many segments dragged to the right as you can.
- Use the PEN tool to draw a curve that connects the other endpoints of the segments that do not touch the horizontal axis.
