Measuring Angles Name_____________________ C A B 0˚ 1) What is an angle? Use the circle drawing to help you understand and explain. 2) How can angles in circle A be the same size as angles in circle B and C when they look wider? 3) When you turn around in a complete circle, you have traveled 360 degrees. Degrees are used to label the distance of a turn. Use a colored pencil to trace the line and label the degrees to show where each of the following turns would stop. Begin at 0˚ each time. Each line represents a turn of 15 degrees. The degrees are the measure of the angle. A. A 15˚ turn B. A 30˚ turn C. A 45˚ turn D. A 90˚ turn E. A 120˚ turn F. A 180˚ turn G. A 210˚ turn H. A 270˚ turn I. A 315˚ turn J. A 360˚ turn
C A B 4) Look at a protractor. How is a protractor similar to the circle above? How is it different? 5) Find the mark on your protractor that would represent the center of the circle. Where is that mark? This is the vertex point mark. 6) Find the mark on your protractor that would represent 0˚. Where is the 0˚ mark? 7) Find the mark on your protractor that would represent 180˚. Where is the 180˚ mark? 8) Each angle sketched below represents a turn. Place your protractor so the center mark is on the vertex of an angle. Line one of the segments up pointing to the 0˚ mark. Now find the mark where the other line segment is pointing. How many degrees is the angle?
