Proving Lines Parallel Worksheet
This free geometry worksheet requires the use of the properties of parallel lines including the Alternate Interior Angle Theorem, Corresponding Angles Theorem, and the Same-Side Interior Angle Theorem and their converses. Problems include the completion proofs and finding the values of missing angles to make a pair of lines parallel.
To prove lines are parallel.
