Measuring Angles with a Protractor

Mr. Ada teaches how to measure and estimate angles using a protractor. The lesson covers measuring acute and obtuse angles, including angles CBA, DAX, DEF, and JKL. Students learn to align the protractor correctly and count degree marks to determine angle measurements. Estimation techniques are also discussed, enhancing students' ability to approximate angle sizes accurately.
