Q1. Two distinct straight lines in a plane make an angle of 80 degrees with each other. How many points do they have in common?
- A.Exactly one
- B.None - they are parallel
- C.Infinitely many
- D.Exactly two
Answer: A. Exactly one
Q2. Two distinct straight lines in a plane make an angle of 100 degrees with each other. How many points do they have in common?
- A.Exactly one
- B.None - they are parallel
- C.Infinitely many
- D.Exactly two
Answer: A. Exactly one
Quick parse - a typical math numerical. The data on the table: 100. We are after How many points do they have in common?. Tool of choice - angle between them = 100 which is not 0. Rearrange it for the unknown before substituting. Numbers in: angle between them = 100 which is not 0 → common points = exactly 1. Common-sense check: so they are not parallel. Lock in option A) Exactly one. Trap-watch: option B) 'None - they are parallel' is incorrect: A non-zero angle means they are not parallel; option C) 'Infinitely many' misses the point - Two DISTINCT lines cannot share infinitely many points.
Q3. Two distinct straight lines in a plane make an angle of 145 degrees with each other. How many points do they have in common?
- A.Exactly one
- B.None - they are parallel
- C.Infinitely many
- D.Exactly two
Answer: A. Exactly one
