Product Tag: Degrees Protractors Clear Protractor Angles Measurement Tool.

How to use

1. Place the center hole on the vertex of the angle.
2. Align the baseline of the protractor with one of the angle’s rays.
3. Read the degree measurement from the scale where the other ray of the angle intersects the curved edge.
4. When measuring, always start counting from the zero on the baseline.
5. To draw an angle, align the baseline with one ray, mark the vertex, and then place a point at the desired degree on the protractor’s scale before drawing the second ray from the vertex through that point.
