Lines and Angles Review

How do you use a protractor to measure an angle?

• Align the protractor's center point with the angle's vertex and read the measurement where one ray crosses the protractor's scale.

• Place the protractor flat on the surface and measure the angle from the edge.

• Hold the protractor at a 45-degree angle to the angle being measured.

• Draw a line from the vertex to the protractor's edge and measure the distance.
