Place the middle part of the protractor (where the lines intersect) on the vertex of the angle, then just look at the number the other arrow’s pointing!
How to measure an angle with a protractor:
Place the midpoint of the protractor on the VERTEX of the angle.
Line up one side of the angle with the zero line of the protractor (where you see the number 0).
Read the degrees where the other side crosses the number scale.
I hope this helps!
