Geometry Points Lines & Angles 3 — Questions and Answers
Question 1: An angle measures 145°. Which classification fits?
- Obtuse (Correct answer)
- Acute
- Right
- Straight
Correct answer: Obtuse
An angle greater than 90° but less than 180° is obtuse.
Question 2: Two parallel lines are cut by a transversal. Corresponding angles are always what?
- Equal (Correct answer)
- Supplementary
- Complementary
- Right angles
Correct answer: Equal
Corresponding angles formed by a transversal cutting parallel lines are congruent.
Question 3: What do you call two coplanar lines that never intersect?
- Parallel lines (Correct answer)
- Perpendicular lines
- Skew lines
- Intersecting lines
Correct answer: Parallel lines
Parallel lines lie in the same plane and never meet.
Question 4: Lines that intersect to form a 90° angle are called what?
- Perpendicular (Correct answer)
- Parallel
- Skew
- Oblique
Correct answer: Perpendicular
Perpendicular lines meet at a right angle.
Question 5: A ray that divides an angle into two equal parts is called the angle's what?
- Bisector (Correct answer)
- Median
- Altitude
- Vertex
Correct answer: Bisector
An angle bisector splits an angle into two congruent angles.
Question 6: If an angle bisector splits a 68° angle, each resulting angle measures what?
- 34° (Correct answer)
- 17°
- 68°
- 44°
Correct answer: 34°
The bisector halves the angle, so 68 ÷ 2 = 34°.
Question 7: Three or more points that lie on the same straight line are described as what?
- Collinear (Correct answer)
- Coplanar
- Congruent
- Concurrent
Correct answer: Collinear
Points on a single line are collinear.
