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