Below are sample questions representative of the exercises included on this worksheet and related 4.144 Angles as Fractions of a Circle skill assessments:

Problem 1Difficulty: Mastery
A student explains that the denominator should be four because a circle has four 90° quarters. Which fraction represents 360°?
Athree quarters of the complete circular turn
Bthe whole of the complete circular turn
Cone quarter of the complete circular turn
Done half of the complete circular turn
Solution & Explanation:A full circle is 360°. An angle of 360° goes all the way around, so it represents 1 whole circle or 4/4 of the circle.
Problem 2Difficulty: Mastery
A turn card gives only the measure 270°. Which fraction of the circle should be selected?
Athe whole of the 360° turn
Bone quarter of the 360° turn
Cthree quarters of the 360° turn
Done half of the 360° turn
Solution & Explanation:A full circle is 360°. Since 270° is three 90-degree parts out of four, it represents 3/4 of the circle.
Problem 3Difficulty: Mastery
A student is sorting angle cards by circle fractions. Into which fraction group should the 180° card go?
Athe whole of the whole-circle model
Bone quarter of the whole-circle model
Cthree quarters of the whole-circle model
Done half of the whole-circle model
Solution & Explanation:A full circle is 360°. Since 180° is half of 360° or two 90-degree parts out of four, it represents 1/2 of the circle.
