Investigate conditions for two lines to be parallel and solve simple numerical problems using reasoning (ACMMG164)

LO: To investigate conditions for two lines to be parallel.

  • That lines exist.
  • That lines can be classified as parallel or non-parallel depending on their angles


  • That parallel lines have identical angles and are equally far apart..
  • That non-parallel lines are not equally far apart.


  • I can determine if two lines are parallel or non-parallel.

Parallel and Non-Parallel Lines.

Perpendicular lines intersect at 90 degrees and parallel lines never intersect no matter how far they are extended.
