This is a Desmos activity to assess the knowledge students have of the slope of parallel and perpendicular lines and angle relationships formed when parallel lines are cut by a transversal.

This resource from the Mathematics Assessment Project was found at OER Commons. https://www.oercommons.org/courses/finding-equations-of-parallel-and-perpendicular-lines/view. This lesson unit is intended to help teachers assess how well students are able to understand the relationship between the slopes of parallel and perpendicular lines and, in particular, to help identify students who find it difficult to: find, from their equations, lines that are parallel and perpendicular; and identify and use intercepts.

Lines and Tigers and Bears, Oh My! Task Template and Student Version of Task

Students will identify and color-code various types of angles formed by parallel lines and a transversal. Also attached is a True/False sort activity based on the types of angles formed by parallel lines and a transversal.

This is a project for geometry students after they have completed their unit on parallel lines and angles formed by parallel lines and transversals.  This project involves creativity and artistic expression.

Identify, describe, and represent points, lines, line segments, rays, angles, and intersecting, parallel, and perpendicular lines. Mathematics Instructional Plans (MIPs) help teachers align instruction with the Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.
