This 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 |
