What does this generator do?
Draws a semicircular protractor with two rays — one along the baseline (0°), the other at a random angle from 20° to 160° (a multiple of 10°).
How to use it
Line the protractor centre up with the vertex and the zero with one ray. Read off the value where the other ray crosses the scale.
