Measuring Angle Openings with Precision: Using a Protractor

This video tutorial teaches how to measure angles using a protractor, focusing on angles that are not multiples of 10. It explains the importance of estimating angles using a corner of paper and provides practical examples, such as belt loaders and recliners, to illustrate the process. The tutorial also highlights common mistakes, like choosing the wrong set of numbers on the protractor, and emphasizes the need to start measurements from zero. By the end, viewers will understand how to read protractors precisely and avoid common errors.
