How to Use a Protractor to Draw Angles
Using a protractor to draw angles can be done in several simple steps. Here, you will be provided with a general guide on how to use a protractor to draw angles.
A Step-by-step Guide to Using a Protractor to Draw Angles
Here’s a step-by-step guide to using a protractor to draw angles:
Step 1: Draw the Base Line
Using a ruler, draw a straight line on a piece of paper. This will be one arm of your angle.

Step 2: Position the Protractor
Place the protractor on the paper so the midpoint of its straight edge (the hole marked usually at 0 and 180 degrees) is exactly at the end of the line you drew. Make sure the straight edge of the protractor is aligned with your line.
Step 3: Mark the Desired Angle
Decide what angle you want to draw. Let’s say you want to draw a 60-degree angle. Find the 60 on the edge of the protractor and make a small mark on the paper at this point.
Step 4: Draw the Second Line
Remove the protractor from your paper. Now, using your ruler, draw a straight line from the end of the first line (the point where you placed the center of the protractor) to the mark you made for the 60 degrees. This line will form a 60-degree angle with your first line.

Step 5: Verify the Measurement
Place your protractor back onto the angle with the center on the vertex (where the two lines meet) and the baseline along the 0-degree line of the protractor. Check the angle to ensure it’s 60 degrees. If it’s not, you can adjust your second line.
That’s it! You’ve used a protractor to draw an angle. With this method, you can draw any type of angle you need. Practice drawing different angles to get more comfortable using a protractor.
