What this Points, Segments and Angles: Core Definitions quiz checks

  • Point, line and plane are undefined terms; every other geometric word is defined from them.
  • If Q is between P and T, then PQ + QT = PT.
  • Complementary angles total 90° and supplementary angles total 180°.
  • A linear pair is supplementary; vertical angles are equal.
  • A midpoint or bisector creates two congruent halves.

The 10 questions of the quiz

  1. Which three terms are undefined in geometry?
  2. If Q is between P and T with PQ = 6.5 and QT = 11.25, what is PT?
  3. M is the midpoint of AB and AB = 39. What is AM?
  4. What is the supplement of a 137° angle?
  5. Two angles form a linear pair. One measures 3 times the other. What is the smaller angle?
  6. Two lines cross. One angle measures 52°. What does its vertical angle measure?
  7. Ray OB bisects ∠AOC and m∠AOB = 27.5°. What is m∠AOC?
  8. Which relationship guarantees that two angles have the same measure?
  9. In the figure, what is m∠AOB if ∠AOC is 90°?
  10. What is the midpoint of the segment on a number line from −9 to 6?
