write your answer inside the angle. Worksheet #2: similar to this slide
Just checking :
Just checking 1. Describe two angles less than 90 degrees in this room. 2. What tool do mathematicians use to measure angles? 3. Hold up your protractor. Point to the 'center mark'. 4. Hold out your two arms and estimate 45 degrees. 5. On the back of your work sheet trace the angle between your little finger and next finger.
draw the angle
estimate the angle measure
measure the angle
how close was your estimate?
