Previous Standard 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 "one-degree angle," and can be used to measure angles.
Next Standard Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
Measurement and Data Geometric measurement: understand concepts of angle and measure angles. 5Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement: bAn angle that turns through n one-degree angles is said to have an angle measure of n degrees.
