   ForLesson 5: What Is an Angle?

   Student Task Statement

    

   

   1. Find one angle in the figure. Draw a pair of rays to show the angle and extend them as far as you can.
   2. Find another angle in the figure. Draw a pair of rays to show the angle. Extend the rays as far as you can. (You can use a different colored pencil for this pair of rays.)
   3. Do you see other angles that you didn’t see before? If so, label each one with a letter.

8. Problem 8
