Questions and Answers

What is a line in geometry?

  • An infinitely thin and long collection of points (correct)
  • A segment with infinite endpoints
  • A ray with two clear endpoints
  • A collection of points with a defined length

    • How are lines typically represented in geometry diagrams?

  • As curved shapes with no defined direction
  • Using arrows to indicate infinite extension in both directions (correct)
  • As segments with visible length
  • With two clearly defined endpoints

    • What distinguishes a line segment from a line?

  • Unclear directionality
  • Clearly defined endpoints (correct)
  • Infinite length
  • Named after their midpoint
