Quiz Analysis & Rotations

50 Minute Class, Curriculum, Geometry

Learning Goal: Identify and analyze errors from our quiz and continue to practice rotations.



  • Common Core
    • HSG.CO.A.2 – Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).
    • HSG.CO.A.3 – Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
    • 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.
  • TEKS
    • G.3(A) – describe and perform transformations of figures in a plane using coordinate notation
    • G.6(C) – apply the definition of congruence, in terms of rigid transformations, to identify congruent figures and their corresponding sides and angles
