MAFS.912.G-SRT.1.2 - Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar.

1. The benchmark will be assessed using Multiple Choice), Multi-select, Open Response, or Selectable Text Response.

2. Items may require students to explain that corresponding angles of two similar figures are congruent and that corresponding sides of two similar figures are proportional..

3. Items may require students to determine if given information is sufficient to determine similarity..


Example One

Example Two

Example Three

The owners of a water park want to build a scaled-down version of a popular tubular water slide for the children's section of the park.  The side view of the water slide, labeled ABC, is shown below.


Points A', B' and C', shown above, are the corresponding points of the scaled-down slide.  Which of the following would be closest to the coordinates of a new point C' that will make slide A'B'C'  similar to slide ABC.

  1. (90, 20)
  2. (77, 20)
  3. (50, 20)
  4. (47, 20)
