MAFS.912.G-CO.1.5 - Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using graph paper, tracing paper, or geometry software. Identify a sequence of transformations that will carry a given figure onto another.
Also assesses: MAFS.912.G-CO.1.3 - Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
1. The benchmark will be assessed using Graphic Response, Hot Text Response, Multiple Choice, Multi-select, Open Response, or Simulation Response.
2. Items should NOT require the student to use the distance formula.
3. Items may require the student to be familiar with using algebraic description, x → x + 3, for transformations
4. Items should NOT use matrices to describe transformations.
5. In items in which the line of reflection is given, it should be in slope-intercept form.
6. In items in which the student has to write the line of reflection, it can be written in any form. If the line is not vertical or horizontal, then the line of reflection should be graphed as a dotted line so slope and y-intercept can be determined.
7. Students may be asked to determine if a given sequence of transformations will result in another figure.
8. Students may be asked to draw or graph a figure using a description of a transformation.

Pentagon ABCDE is shown below on a coordinate grid. The coordinates of A, B, C, D, and E all have integer values.
If pentagon ABCDE is rotated 90º clockwise about point A to create pentagon A'B'C'D'E', what will be the x-coordinate of E'?
