Is there a printable protractor?
This printable protractor can be cut out and used by students during geometry class and other math lessons where measurement of angles is needed. Students can use this as a resource for measuring angles in school and at home. This is meant for use by grades 3-6.
Can I make my own protractor?
Protractors are a tool used in mathematics to measure angles in degrees. You might need a protractor to work on homework or make construction plans, so learning how to make your own can come in handy. You can make a protractor by printing from a template or folding a square of paper to always have one on hand.
What are the two types of protractor?

What to do if you don’t have a protractor?
However, if you don’t have a protractor handy, you can determine the size of an angle using the basic geometric principles of triangles. You’ll need a scientific calculator to solve the equations. Most smartphones are equipped with them, but you can also download a free app or access a free calculator online.
What is a bevel protractor?
The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 arcminutes (5′ or 1/12°) and can measure angles from 0° to 360°. The bevel protractor consists of a beam, a graduated dial and a blade which is connected to a swivel plate (with Vernier scale) by thumb nut and clamp.
Does the size of a protractor matter?
If you are drawing an acute angle (less than 90 degrees), use the scale with the smaller numbers. For obtuse angles (greater than 90 degrees), use the scale with larger numbers. Remember, the baseline is parallel to the edge, but is not the flat edge of the protractor.
What is the triangle protractor?
A triangle protractor is called a nautical protractor which is used by seamen for navigational charts. The markings of 45° angled lines make the access of 45, 90, and 135 easier for them.
