Estimating angle measures is based on comparing them to some ballpark angles, such as the right angle, the 45° angle, and the 30° angle (which is the angle between two consecutive numbers on the clock face).
First, I estimate a few angles. Then I draw a few angles by estimating them (not measuring), and check afterwards.
Lastly in this video I explain the concept of turning in a specific angle, such has turning in a 30° angle.
