For this assignment, the directions read: "For each row in the table below, look at the angle measure given. Then in the Draw It! section of the table, use a protractor to draw the given angle and label it with its measure. In the Classify It! section, tell whether each angle is an acute angle, obtuse angle, or right angle (explain how you know the measure is less than 90, the measure is 90, or the measure is greater than 90 but less than 180.
A quick mnemonic for measuring angles with a protractor - Extend the rays, Estimate the answer (above or below 90 degrees) and now it's Easy to determine which number on the protractor to choose. Common Core Math standards require students to know and measure angles - but it is always confusing on how to do it easily and how to pick between the two numbers on the protractor.
