Question
How can you find the degree measure of the angle given below using a protractor?
Answer

We can measure ∠1 = 100° using protractor and subtract it from 360° to find the measure of ∠2 = 260°.
Alternative: We can draw a ray opposite to one of the arms and split the angle into two parts – straight angle and an acute angle. The measure the acute angle (∠1 = 80°) using protractor and add it to 180°. It would be the measure of required angle (180° + 80° = 260°).
