Additional Vocabulary Support: Parallel and Perpendicular Lines.
Categorize the figures described in each scenario. Each category should contain only one item.
  • Two lines in the same plane that never intersect.
  • A line that crosses two lines in the same plane at two different points.
  • What two lines do that cross at a point.
  • Two lines that cross at a 90° angle.
  • intersect
  • parallel
  • perpendicular
  • transversal
