    Unit Plan & Video Lesson Links


    This is a complete parallel and perpendicular lines unit for Geometry. This is the 3rd unit in my Geometry curriculum.

    *Note: This unit is best suited for on-level or lower-level/special education math classes. Supplements will most likely be needed for an honors or upper-level math class.

    *Update: Video lessons are now included for each set of notes!*

    Topics include:

    • special angle pairs (vertical, adjacent, linear pairs)
    • parallel lines cut by a transversal (alternate interior, alternate exterior, consecutive interior, consecutive exterior, corresponding)
    • angle measures (including algebra)
    • special angle pairs proofs
    • finding if lines are parallel, perpendicular, or neither
    • writing the equations of parallel and perpendicular lines
    • perpendicular bisector proof

    Products include:
