Definition
The Corresponding Angles Converse states:
“If two lines are cut by a transversal and the corresponding angles are congruent, then the lines are parallel.”
In other words:
If a transversal crosses two lines,
And the corresponding angles are equal in measure,
Then the two lines must be parallel.
Why it's useful:
This converse allows you to prove that two lines are parallel based on angle relationships. It’s often used in geometric proofs and reasoning.
