m$\angle$D= 60, m$\angle$E= 80, m$\angle$F= 40
Work Step by Step
Using a protractor, measure each of the angles. 1. Place the midpoint of the protractor on the corner of the angle. 2. Line up one side of the angle with the zero line of the protractor (where you see the number 0). 3. Read the degrees where the other side crosses the number scale.
