After enlarging his "U" in problem 3-26, Al has an idea. He drew a 60° angle, as shown in Diagram #1 at
right. Then, he extended the sides of the angle so that they are twice as long, as shown in Diagram #2.
"Therefore, the new angle must have measure 120°," he explained. Do you agree? Discuss this with your
team and write a response to Al.
