How do you measure an angle using a protractor?
Align the protractor's center point with the angle's vertex and read the degree measurement where one ray intersects the protractor.
Place the protractor flat on the surface and measure the angle from the horizontal line.
Use the protractor to draw a line that represents the angle and then measure it.
Estimate the angle by comparing it to a known angle on the protractor.
