What angle is shown on the protractor?
°
What does this generator do?
The generator displays an angle on a protractor (multiple of 10°, between 20° and 160°). You read off its measure.
How to read a protractor
Place the vertex of the angle at the centre of the protractor (the black dot). Align one arm with the zero line. The other arm crosses the protractor at a specific number — that is the measure of the angle in degrees.
