Full turn angles
Time needed: 1h30m.
Difficulty: Intermediate
Several techniques are explored in this tutorial. The simplest of them, but also the most limited, uses coordinates to determine whether the angle measures more or less than 180 degrees. It's usefull for geometric constructions using the Graph view.
The second technique allows us to create angles from 0 to 360 degrees in the Plane Geometry view, where we have no coordinates to determine in which half plane the relevant points are. It's a more sophisticated technique but also more general, being useful even when a coordinate system exists.
Finally, a technique to calculate formulas in terms of angle measurements in such way that the results don't change when the angle units are set to Degrees, or Radians is shown.
