To measure an angle using a protractor, follow these steps:
- Line up the vertex of the angle with the dot at the center of the protractor.
- Line up one side of the angle with 0 degrees on the protractor.
- Read the angle from the protractor.
- Draw a straight, horizontal line using a ruler or the straight edge of your protractor.
- Use the straight edge of the protractor to make the lines longer on the angle.
- For angles greater than 180 degrees, place the protractor on the arm of the angle upside down and mark the point on the curved edge of the angle.
- Place the center of your protractor at the vertex of the angle, where the two lines come to a point.
- In the animation below, we use a protractor to measure two angles. A protractor usually has two scales, starting at zero at opposite ends.
In summary, using a protractor to measure angles is a simple and effective method that can be used in various fields. By following these steps, you can create accurate and accurate angles in your work.

Thank you so much for this, it helps a lot to me cause im just gr.4 but I really need this cause we have math class later and I dont know how to use and how to measure by using protractor. Thank you again for this it helps a lot of people who is struggling to math. 🙂 ♥ (Edited) Posted this at Jan 24, 2022
Something I came here to learn but wasn’t addressed was why the students shouldn’t select the 120 degrees on the protractor. What needs to be taught early is whether the angle is more than or fewer than 90 degrees just by looking at it. Nearly all students trip up on this. The next tough step is how to measure an angle where the rays do not sit horizontally….
I’m not sure why I decided to watch this article…….. I’m 31 years old and I actually graduated high school a year early. I know how to use a protractor. I think the only reason I actually watched this was because I found an old protractor and decided to look at articles about them. I CAN SAY…….. I am HAPPY I DID! I had one of those “ODDLY SATISFYING” moments. I stuck my clear protractor against my phone screen and lined it all up. Every time he was talking about a certain point and either circled it or highlighted it………. it just look so weirdly cool. It was like my protractor became a part of the article. 🤷🏻♂️ Who knew…… I like oddly satisfying math moments!!!! 😂👍🏻

This article is confusing, how will I know which one to use? The top row 60, or the bottom row. Why is there 2 rows of numbers that are the opposite way anyway. I’ll explain if u don’t know what I mean, why is there 2 rows of numbers in opposite ways? The numbers below are 0,10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, and much more all the way to 180. And the top row is the opposite of bottom row. How would I know which row to use??? I have the protractor, but the protractor is confusing and idk how to use it. I’m not a teenager or smth above 18, I’m 9.
