Questions
  1. Question
    Eliminate the true statements about angles.
    Choices
    1. Item
      A clockwise turn gives a positive angle
      Correct
      Yes
    2. Explanation
      That is what the point the ray turns about is called.
      Item
      The point of rotation is called the vertex
    3. Explanation
      Both are named as the commonly used units of angle.
      Item
      Degree and radian are both angle measures
    4. Explanation
      Both are defined for all real numbers.
      Item
      Sine and cosine accept every real number
Instructions
Remove the statements that are true. One false one should survive.
