A transparent virtual protractor that can be placed over angles to teach students how to measure and draw geometric figures.
How to Use: Click and drag the protractor to move it. Use the rotation handle to align the baseline with an angle’s ray. Read the degrees from the inner or outer scale.
Classroom Idea: Provide a variety of angles on the screen and have students measure each, identifying them as acute, right, or obtuse based on the protractor’s reading.
