Short explanation on comparing angles.
Focus on: the definition of an angle's size and what 'amount of rotation' means.

Write down your personal rule to remember which scale to use when measuring.
State a clear rule for placing the baseline and finding the zero mark.
Reflect on how your rule avoids measuring the wrong side of the angle or confusing acute/obtuse angles.
