Place the protractor so that one of the arrows points to zero.
127^(∘)
Practice makes perfect
We can place a protractor on top of the arrows to measure the angle.
It might be difficult read the angle since the arrows are so short. We like to use a ruler to extend the line and get a more accurate measurement.
The arrow points to the angle 53^(∘)/127^(∘). Since the first arrow points to the zero on the right, we measure counterclockwise to find the inner angle.
We can also think about which measurement is correct by recognizing that this angle is obtuse and should be greater than 90^(∘). The measure of the angle is 127^(∘).
