Concept Quiz: Equations of Parallel & Perpendicular Lines, Translations, & Reflections

Curriculum, Geometry, 50 Minute Class

Quiz Message


Learning Goal: Assess conceptual and procedural fluency for translations, reflections, and writing equations of parallel & perpendicular lines, and reassess parallel lines & transversals.


Note:

The SBG grades for Equations of Parallel & Perpendicular lines, Translations, and Reflections will count toward the 2nd nine weeks in order to give enough time for pursuit of further learning and retakes.

Classwork:

  • Concept Quiz (will be posted after the kids take it)
  • Optional Challenge (will be posted after the kids take it)
  • Retake: Parallel Lines & Transversals (will be posted after the kids take it)

Standards:

  • Common Core
    • 8.G.A.5 – Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
    • HSG.CO.A.5 – Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another.
    • HSG.GPE.B.5 – Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).
  • TEKS
    • G.2(C) – determine an equation of a line parallel or perpendicular to a given line that passes through a given point
    • G.3(A) – describe and perform transformations of figures in a plane using coordinate notation
    • G.6(A) – verify theorems about angles formed by the intersection of lines and line segments, including vertical angles, and angles formed by parallel lines cut by a transversal and prove equidistance between the endpoints of a segment and points on its perpendicular bisector and apply these relationships to solve problems
