Activity 1: What's the Angle? PURPOSE Develop angle measurement using the central angle in a circle and its intercepted arc. COMMON CORE SMP GROUPING GETTING STARTED SMP 3, SMP 4, SMP 5, SMP 6, SMP 7, SMP 8 Work individually. The measure of an angle is the amount of rotation as a ray turns from coinciding with one side of the angle to coinciding with the other side. A complete rotation of a ray about a point results in an angle with a measure of

`360\deg `

. One degree is

`(1)/(360)`

of a complete rotation. A central angle is an angle whose vertex is the center of a circle and whose sides contain radii. Example: For each central angle, record its measure and its classification: acute, right, or obtuse. For each exercise, construct an angle that has the given measurement. In some exercises, one side of the angle is given.
