Help me asap how to understand Measuring Angles
Whitepunk [10]

this depends. you can measure angles in real life with a protractor or just use your eye. let us start with the protractor. place the midpoint of a protractor on the vertex of the angle and make sure it lines up to 0. on the other side read the degrees (make sure everything aligns). without a protractor you can use the Sine Formula and measure the lines.
