This shows how to use a protractor to draw an angle - 42° in this example. We start with a line segment ML. Using a protractor, we draw another line MV at an angle of 42° to it.

Step-by-step Instructions Printer friendly version
Step 1 Place the protractor so that the origin (small hole) is over the point M.
Step 2 Rotate the protractor so that the base line is exactly along the line ML.
Step 3 Using (in this case) the inner scale, find the angle desired - here 42°.
Step 4 Make a mark at this angle, and remove the protractor
Step 5 With a ruler, draw a line from M to the mark you just made. Label this point V.
Step 6 Done. The line drawn makes an angle LMV with a measure of 42°
