How do you draw an angle without a protractor?
Start at the fixed ray and estimate how far the second ray needs to turn. For 90°, use the corner of a square. For 45°, aim halfway between that corner and the starting ray. For 225°, continue past a straight line by another 45°.
How is your drawing scored?
Each round gives you three targets. A drawing within 10° of the target counts as a hit. When you check a drawing, the gold arc shows the target and the dashed arc shows your drawing. You see your average error after all three.
