Flashcards

Review key concepts visually

Definition, notation, and visualisation of line segments, rays, and lines.Characteristics, notation, and visualisation of perpendicular and parallel lines.Measuring distances between points and lines, showing examples of point to point, point to line, and between parallel lines.

🛎️ What are Different Types of Lines?

  • A line segment has two endpoints, a ray has one endpoint, and a line has no endpoints.
  • Rays and lines continue forever, but a line segment has a fixed length.

🛎️ What are Perpendicular and Parallel Lines?

  • Perpendicular lines meet at a right angle (90°).
  • Parallel lines stay the same distance apart and never meet.

🛎️ How to Measure Distance Between Points and Lines

  • The distance between two points is the length of the line segment joining them.
  • The distance between parallel lines is the length of the perpendicular line segment between them.
