Checking for Parallel lines:

There are three conditions to check whether the two lines are parallel.

  • When a transversal cuts two lines, such that pairs of corresponding angles are equal, then the lines have to be parallel.

  • When a transversal cuts two lines, such that pairs of alternate interior angles are equal, the lines have to be parallel.

  • When a transversal cuts two lines, such that pairs of interior angles on the same side of the transversal are supplementary, the lines have to be parallel.
