Measuring Angles

“Imagine you are measuring an angle with a protractor. The angle is obtuse, and one ray lines up with the 0° mark. The other ray passes between the 120° and 130° marks, but closer to 130°. Estimate the measure of the angle. Explain your reasoning. You are measuring an angle using a protractor. One ray lines up with the 0° mark on the right side of the protractor. The other ray intersects the protractor halfway between the 50° and 60° marks on the *inner* scale. What is the measure of the angle? Is it acute, right, or obtuse? An angle is measured using a protractor. One ray lines up with the 10° mark, and the other ray lines up with the 100° mark on the same scale. What is the measure of the angle? Explain how you found your answer.”
