Using a Protractor to Draw an Angle
Click here for a printable angle drawing worksheet
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
| 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° |
