How do you measure an angle using a protractor?

• Use a ruler to draw a line and measure the angle with it.

• Align the protractor's midpoint with the angle's vertex and read the measurement where the other side intersects the scale.

• Estimate the angle by eye without using the protractor.

• Place the protractor upside down and measure from the bottom edge.
