4th Grade


Arkansas Academic Standards:
4.MD.C.5.A

 An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle
 An angle that turns through 1/360 of a circle is called a "onedegree angle," and can be used to measure angles
