On his test, Mark was asked to measure BAC and label it as acute, right, obtuse, or straight. He lined up his protractor as shown, and then labeled the angle as obtuse. Your job is to give Mark some descriptive and effective feedback. Did he choose the best word? If so, write a clear and precise justification for Mark supporting his word choice. If you do not think he chose the best word, correct Mark, and justify your choice clearly and precisely for the angle's label.
