Question

Look at quadrilateral PQRS and its scaled image P'Q'R'S'. What scale factor was used for the scaled image? Explain how you determined this.

Answer 1

The scaled factors would be 2.5 becuz the triangles are similar, you can use the proportion to find that 15/6 = 2.5 and 10/4 = 2.5, and 20/8 = 2.5. Since the proportions are the same the scale factor would be 2.5.

Answer 2

The scale factor would be 2.5. Since the triangles are similar, you can use the Proportionality Theorem to find that 15/6 = 2.5, 10/4 = 2.5, and 20/8 = 2.5. Since the proportions are equal, the scale factor would be 2.5. More specifically, it's a reduction of 2.5.
