About this worksheet

What students practice

  • Students identify congruent figures using rotations, reflections, and translations.
  • Students describe and verify sequences of rigid motions using corresponding vertices.
  • Students explain why the order of transformations can change the final image.

How to use

Use after introducing rigid motions. Have students trace figures or sketch intermediate images on grid paper, then discuss the final reasoning question.

Curriculum

Common Core standard covered

8.G.A.2

Understand congruent figures as ones linked by rotations, reflections, and translations, and describe such a sequence.

Weather Station: Matching Display Shapes

Use rigid motions to compare shapes on temperature and rainfall displays.

Move the Display Shapes

A weather station records temperature and rainfall. These grids show the layout of its display symbols, not weather measurements. All coordinates are in grid units. Match corresponding vertices in the order named.

1.
The temperature display uses triangle ABC. Its new position has A′(1, −1), B′(4, −1), and C′(1, 1). Which motion maps every vertex to its corresponding vertex?−6−5−4−3−2−11234560−6−5−4−3−2−1123456ABC
  • A. Translate 5 units left and 3 units up.
  • B. Translate 5 units right and 3 units down.
  • C. Translate 5 units right and 3 units up.
  • D. Translate 3 units right and 5 units down.
2.
A rainfall symbol is translated without turning or flipping. One vertex moves from (−3, −2) to (2, 1). Another vertex starts at (−1, −4).

Write the final coordinates of the second vertex: ( ,  ).

3.
A copy of the rainfall marker has P′(1, 2), Q′(1, 5), and R′(3, 2). Which rotation maps the shown marker to this copy?−6−5−4−3−2−11234560−6−5−4−3−2−1123456PQR
  • A. Rotate 360° about the origin.
  • B. Rotate 90° clockwise about the origin.
  • C. Rotate 90° counterclockwise about the origin.
  • D. Rotate 180° about the origin.
