Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
Subject Area: Mathematics
Grade: 8
Domain-Subdomain: Geometry
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Understand congruence and similarity using physical models, transparencies, or geometry software. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

  • Item Type(s): This benchmark may be assessed using: GRID item(s)

  • Assessment Limits :
    Coordinate values of ?? and ?? must be integers. The number of transformations should be no more than two. In items that require the student to draw a transformed figure using a dilation or a rotation, the center of the transformation must be given.

  • Test Item #: Sample Item 2
  • Question:

    Quadrilateral ABCD is rotated 90° clockwise about the origin to create quadrilateral A’B’C’D’.

    Use the Connect Line tool to draw quadrilateral A’B’C’D’.

  • Difficulty: N/A

  • Test Item #: Sample Item 3
  • Question:

    A pentagon is shown.

    The pentagon is translated 5 units to the left and then reflected over the x-axis.

    Use the Connect Line tool to draw the pentagon after its transformations.
