    Angle protractor applications

    Tips: What is the maximum angle measurement capacity of a metal angle protractor?

    The maximum angle measurement capacity of a metal angle protractor can vary depending on the specific protractor. However, most metal angle protractors typically have a maximum angle measurement capacity of 180 degrees. This allows them to measure angles ranging from 0 degrees to 180 degrees. Some protractors may have additional markings or features that allow them to measure angles beyond 180 degrees, but these are less common.
