Example Question #1 : Similarity, Right Triangles, & Trigonometry

If the red figure is an object and the blue figure is an object after dilation, what is the scale factor?

Plot2

Possible Answers:

Correct answer:

Explanation:

The best way to solve for the scale factor is to find the same vertex from each object, and divide their components.

Let's use  and 

Let's divide the x-coordinates together.

Since we are going from the smaller object to the larger object, we know that our scale factor is going to be greater than one.

So our final answer is going to be.
