About this worksheet

What students practice

  • Students determine image coordinates under translations, reflections, rotations, and dilations.
  • Students identify transformations from corresponding coordinates and combine coordinate rules.
  • Students use coordinate evidence to check whether a resizing is a dilation.

How to use

Use after teaching the four coordinate transformations. Have students sketch intermediate images on graph paper and discuss the final test-record error.

Curriculum

Common Core standard covered

8.G.A.3

Use coordinates to describe how dilations, translations, rotations, and reflections change 2-D figures.

Robotics Club: Prototype Coordinate Tests

Track robot parts and test diagrams using coordinate transformations.

Position the Parts

Each coordinate pair gives a location on a robot design grid. A prime mark (′) names an image point. Apply each transformation to the entire part.

1.
The plotted points are corners of the robot's battery bracket. The club slides the bracket 3 units left and 4 units up. Select every correct corner record.−6−5−4−3−2−11234560−6−5−4−3−2−1123456ABCD

2.
A sensor plate has corners P(−5, 0), Q(−2, 0), and R(−2, 2). Its three mounting holes are at (0, −3), (3, −3), and (3, −1), respectively. Which command aligns all three corners with their holes without turning the plate?
  • A. Translate 5 units right and 3 units up.
  • B. Translate 5 units right and 3 units down.
  • C. Translate 5 units left and 3 units down.
  • D. Translate 3 units right and 5 units down.
3.
The club makes a mirrored gripper plate by reflecting the plotted vertices across y = −x. Which list gives E′, F′, and G′ in that order?−5−4−3−2−1123450−5−4−3−2−112345EFG
  • A. (−2, 3), (−2, −1), (−4, −1)
  • B. (3, −2), (−1, −2), (−1, −4)
  • C. (2, −3), (2, 1), (4, 1)
  • D. (−3, −2), (1, −2), (1, −4)
