Sample questions with solutions
Q1. When two lines on a plane meet at a point, we say they ______ each other.
Show answer
Answer: intersect
Why: Lines that meet at a point intersect. [p.106]
Why: Lines that meet at a point intersect. [p.106]
Q2. Two lines intersect and one angle is 120°. What is the measure of the angle forming a linear pair with it (in degrees)?
Show answer
Answer: 60 (± 0)
Why: A linear pair makes a straight angle: 180 − 120 = 60°. [p.107]
Why: A linear pair makes a straight angle: 180 − 120 = 60°. [p.107]
Q3. Two lines intersect and one angle is 120°. What is the vertically opposite angle (in degrees)?
Show answer
Answer: 120 (± 0)
Why: Vertically opposite angles are equal: 120°. [p.107–108]
Why: Vertically opposite angles are equal: 120°. [p.107–108]
Q4. Two intersecting lines form four equal angles. What is each angle?
- 90°
- 45°
- 180°
- 60°
Show answer
Answer: A. 90°
Why: Four equal angles around a point: 360 ÷ 4 = 90°, so the lines are perpendicular. [p.109]
Why: Four equal angles around a point: 360 ÷ 4 = 90°, so the lines are perpendicular. [p.109]
Q5. Parallel lines are a pair of lines that ______.
- lie on the same plane and never meet however far they are extended
- meet at 90°
- meet at one point
- lie on different planes
Show answer
Answer: A. lie on the same plane and never meet however far they are extended
Why: Parallel lines lie in the same plane and never meet. [p.110]
Why: Parallel lines lie in the same plane and never meet. [p.110]
Q6. The opposite edges of a square sheet are ______ and adjacent edges are ______.
- parallel; perpendicular
- perpendicular; parallel
- both parallel
- both intersecting at 45°
Show answer
Answer: A. parallel; perpendicular
Why: Opposite edges never meet; adjacent edges meet at right angles. [p.111]
Why: Opposite edges never meet; adjacent edges meet at right angles. [p.111]
