I learned that first you line it up to the first ray. Then you line it up with the second ray. Finally count the and on the second ray. You have to make sure that the vertex is in the middle of the protractor.

I learned that the dot has to be in the vortex or the corner and the 0 has to line up with one of lines and measure the other line.
