Measuring and Classifying Angles

The video tutorial covers how to measure angles using a protractor. It begins with an introduction to angle measurement, followed by detailed steps to determine whether an angle is acute, right, or obtuse. The tutorial provides examples of measuring angles, including advanced strategies for angles not starting at zero. The video concludes with practice exercises to reinforce the concepts learned.
