Question

This is the same dilation that you use in question 3. What scale factor was used to create the dilated triangle MSV’? In your answer, keep the scale factor that was used in explain how you calculated.

Answer 1

From the information given, triangle M'S'V' was dilated to give triangle MSV. Since triangle MSV is an enlargement of triangle M'S.V, it means that the scale factor is greater than 1. To find the scale factor, we would find the ratio of the x and y coordiantes. We have

Scale factor = M/M' = - 3/- 2 = 3/2 = 1.5

Scale factor = 1.5
