A protractor is a semicircular geometry tool divided into 180 equal parts, each measuring 1°. It is used for drawing angles of known measures and finding angles of unknown measures and is usually made of transparent plastic, glass, steel, or wood.The geometry protractor have two scales marked on it: outer and inner. The outer scale starts from 0° a...
Step 1: Place the center point of the protractor over the angle’s vertex. Step 2: Adjust the protractor (without shifting the center from the vertex) so that one arm of the angle is along the baseline of the protractor. Step 3: Look at the scale where the baseline arm points to 0 degrees. Step 4: Read the measure of the angle where the other arm cr...
You can follow the following steps for drawing an angle with a protractor. Suppose you have to draw an angle of 50°. 1. Use a ruler to draw a horizontal line AB on the paper. 1. Take a protractor and place it such that its center point coincides with point A and its baseline coincides with AB. 1. Mark point C, where you find a 50° angle on the prot...
Example 1: Find the measure of each angle of an equilateral triangle with the help of a protractor. Solution: Align the protractor with the vertices of △ABC. Note the angle obtained in each case. You will find that all the angles of the equilateral triangle measure 60°. Example 2: What will be the angle created at vertex B of the square? Solution: ...
are there negative angles, and if so is there a protractor that will measure them?

- Thomas Blundeville invented the protractor.
- Good question. 360º and 0º will be on the same place on a diagram, but they mean different things. Think of it this way. You walk onto a basketball...
- no, there are no negative angles. once they go all the way around and pass the point, it goes back to 0 and starts all over again.
- For example, imagine that you are taking a point in the map. A simple 1 degree error, in 1 mile, that represents easily more than 10m in topographi...
- By humans? Of course. Maybe by nature as well... A leading theory on why moths follow light is based on the concept that the moth keeps a constant...
- That would go into negatives
- You can guess with the human eye, but using a protractor will give you a more precise answer.
- They don't. You can start at any angle but it would be harder because you would have to subtract the small number from the larger one; so that's wh...

Protractors are fun and easy to use. Have a look at this animation (press the play button) to see how to make a neat angle using a protractor and ruler: Measuring. Protractors usually have two sets of numbers going in opposite directions. Be careful which one you use!
A protractor is a tool used to measure angles. Most protractors measure angles in degrees (°). When using a protractor, notice that the outside set of numbers goes from 0 to 180 degrees where the 0 is on the left side of the protractor while the inner set goes from 180 to 0 degrees where 0 is on the right side of the protractor.
