Plato's Protractor™ - III

The Mathomat kids are encouraged to understand the nature of what they are measuring by considering that the units for angle size that they have encountered so far in the Explorer manual (windmill angles, degrees, and quips) all measure the same aspect of angle, being its openness. The Mathomat kids use the TGT in Mathomat as a tool for helping them to convert between quips and degrees when measuring angle.
