    3. C. 21
    4. D. 19
  5. Which pair of statements is equivalent to the biconditional "An angle is right if and only if it measures 90°"?
    1. A. If an angle is right, then it does not measure 90°; if it measures 90°, then it is right.
    2. B. If an angle is right, then it measures 90°; if an angle measures 90°, then it is right.
    3. C. If an angle measures 90°, then it is right; if an angle is not right, then it measures 90°.
    4. D. If an angle is right, then it measures 90°; if an angle is not right, then it measures 90°.
