Converse Transversals

If angle 1 is congruent to angle 3, Then... ?

• Line m is parallel to line n, because corresponding.

• Line m is parallel to line n, because alternate exterior.

• line a is parallel to line b, because alternate interior.

• line a is parallel to line b, because corresponding.

If angle 1 and angle 8 are congruent....

• Then, line l and line m are parallel, because alternate exterior angles.

• Then, line n and line m are parallel, because alternate interior angles.

• Then, Then, line l and line m are parallel, because consecutive angles.

• Cannot deduce anything from this information.
