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.

What is the estimated measurement of angle DEF?

How do you determine if an angle is acute or obtuse?

What was the actual measurement of angle JKL compared to the estimate?
