Can you print off a protractor?
Here are some protractors you can download, print, and use. I suggest printing on transparency film. These protractors should not be used on-screen because computer displays generally distort image dimensions in such a way as to make the measurements imprecise.

What can I use in place of 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 grade uses protractors?
Students can use this as a resource for measuring angles in school and at home. This is meant for use by grades 3-6.
What is the use of protractor?
protractor, any of a group of instruments used to construct and measure plane angles. The simplest protractor comprises a semicircular disk graduated in degrees—from 0° to 180°. It is an ancient device that was already in use during the 13th century.
How do you measure if you don’t have a protractor?
To measure an acute angle without a protractor, start by drawing a vertical line connecting the 2 rays of the angle to form a right triangle. Note that the angle formed by the adjacent side of the triangle and the opposite side measures 90 degrees. Next, measure the length of the adjacent side to find the run.
Are protractors still used?
This kind of protractor are commonly used for mechanical and architectural drawing but today is more and more replaced with computer aided design or CAD. Toolmakers are also using this protractor. Very close tolerances are possible to measure with this tool.
Why do we use protractors?
A protractor is a device used in drafting and drawing: it’s mainly used for drawing and measuring angles. Don’t show up to geometry without your protractor! In math class, you use many tools, such as a calculator. Another is the protractor, which is handy when you’re studying geometry.
How do you mark an angle without a protractor?
Read through the following steps.
- Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.
- Place the compass on the point where one arc crosses an arm and draw an arc inside the angle.
- Use a ruler to join the vertex to the point where the arcs intersect (D).
