As shown below a protractor is a half or full circle measuring device marked in degrees along the outer edge with a straight line running from 0 to 180. First put the vertex at the center of the protractor. To measure AOB place the protractor in such a way that its center is exactly on the vertex O of the angle the baseline lies along the arm OA.

Which of the following could be the measure of the angle if we know it is an acute angle. A half circular protractor is marked for 180 degrees and a full circle for 360 degrees. It is calibrated in Main Scale Divisions and Vernier Scale Divisions.

This ratio will give you the radian measure of the angle. Describe and draws parallel intersecting and perpendicular lines using ruler and set square. The vertex is the point where the two arms meet.
