This document contains an 18 question skills assessment on parallel and perpendicular lines. It begins with level 1 review questions testing the student's knowledge of basic angle types and properties of parallel lines. Level 2 questions focus on using properties of parallel lines to determine angle relationships such as alternate interior angles being congruent. Level 3 questions apply these concepts in context. Level 4 extends the skills by requiring students to use multiple angle properties to find unknown angle measures. The assessment covers key angle terminology and angle relationships involving parallel lines.
