In Exercises 23 to 34, give the indirect proof for each problem or statement.
In a plane, if two lines are intersected by a transversal so that the corresponding angles are congruent, then the lines are parallel.
To verify:
In a plane, if two lines are intersected by a transversal so that the corresponding angles are congruent, then the lines are parallel.
Consider the figure below.
Two lines
