## Properties of Parallel Lines - Corresponding, Alternate, Same Side Interior Angle Worksheet

This free geometry worksheet contains problems on parallel lines and their properties. Students must have an understanding of the properties of angles formed by parallel lines and a transversal (alternate interior angles, corresponding angles, and same-side interior angles). The worksheet requires students to identify these angles, to find the measures of unknown angles, and to complete two-column proofs
