Spiralitudity

1. It is possible to draw a curve from a series of short, straight line segments. If the angle between segments and the segment length

are both the same, you get a circle. If the segment length increases or the angle decreases (or both), you get a spiral.

2. Write code to draw a spiral. Keep the angle between segments the same and increase the length of each segment. Hints: Use the

clear, pen down, and pen up blocks to do the drawing and a repeat block to draw each segment.

3. Modify your code so that the length increases and the angle decreases.

4. Name your project Spiralitudity and save it.
