Measuring angles review (article) | Angles | Khan Academy
WEBMeasuring angles. Angles are measured in degrees. We can use a protractor to measure how many degrees an angle is. Example: Measure the following angle in degrees: First, we line up the dot on the center of the protractor with the vertex of the angle.
