Protractor

This interactive online protractor makes it easy for students to learn how to measure angles.

Toggle the degree function off or on by clicking the button in the top right hand corner. To view only an angle tool, toggle the protractor off by clicking the button on the upper left hand side. Change the angle by clicking and dragging the dotted circles as desired.

When students are learning to use a protractor, it can be helpful to use the degree function. Then, as they learn to use the tool, you can have them try turning it off. They can always turn the function back on to check their work.

Here are a few ways to use the interactive online protractor:

• Ask students to create and measure 5 acute angles using the protractor.
• Ask students to create and measure 5 obtuse angles using the protractor.
• Ask students to create specific angles without using the degree function. For example, create an angle that measures 132 degrees.
