Proving Lines are Parallel (Converse Theorems)

Use converse angle theorems to prove whether given lines are parallel. Determine line parallelism based on congruent or supplementary angle relationships.

Questions

    If angle 1 = 110 degrees and alternate exterior angle 8 = 110 degrees, are the lines parallel?

  4. MultiChoice

    If angle 3 = 65 degrees, what measure of consecutive interior angle 5 will prove line L1 is parallel to L2?

  5. MultiChoice

    If two same-side interior angles are 85 degrees and 95 degrees, are the two lines parallel?

  6. MultiChoice

    If corresponding angles measure 70 degrees and 110 degrees, are the lines parallel?

  7. MultiChoice

    Which theorem proves lines are parallel when matching corresponding angles are equal?

  8. MultiChoice

    What must angle 6 equal so that alternate interior angle 3 = 88 degrees proves parallelism?

  9. MultiChoice

    If same-side exterior angle 1 = 130 degrees, what value of angle 7 proves the lines are parallel?

  10. MultiChoice

    Which statement CANNOT be used as proof that two lines are parallel?

  11. MultiChoice
