MAFS.912.G-SRT.2.5 - Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
1. The benchmark will be assessed using Drag and Drop Response, Equation Response, Movable Text Response, Multiple Choice Response, Open Response, or Selectable Text Response.
2. Items may require students to use congruence criteria for triangles to solve problems or to prove relationships in geometric figures.
3. Items may require students to use similarity criteria for triangles to solve problems or to prove relationships in geometric figures.
4. Items may use geometric figures of any shape that can be deconstructed to form a triangle.

Malik runs on the trails in the park. He normally runs 1 complete lap around trail ABCD. The length of each side of trail ABCD is shown in meters (m) in the diagram below.
If trail EFGH is similar in shape to trail ABCD, what is the minimum distance, to the nearest whole meter, Malik would have to run to complete one lap around trail EFGH?
