Example Questions

Example Question #11 : Similarity, Right Triangles, & Trigonometry

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


Plot11

 

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 larger object to the smaller object, we know that our scale factor is going to be less than one.

So our final answer is going to be.
