How do you use a protractor?

Question

I'm in 10th Grade and I'm in Geometry. We're going to have a sub in our class for awhile because my teacher is really sick. So today we started a new section. Its about angles. YOu know like obtuse, acute and all those. Well I'm trying to measure an angle but I have no idea how because our sub didn't even explain to us how to use a protractor. If I ever did use a protractor I completely forgot how to so please help me. :)

Answer 1

Most protractors have the little stick that moves to find the right measurement, but if not just place the circle in the center on the vertex of the angle then follow the line to whatever degree it is, and that's the measurement of the angle.
