Question

A'B'C' is a dilation image of ABC. Which is the correct description of the dilation?

Answer 1

The second option is the answer.

Explanation:

The center of a dilation makes all the corresponding vertices coincide at one point if we draw a straight line including that pre image and new image point. All coordinates correspond about Point C. So the first two options are the viable answers.

The blue triangles right side measure is 10 while the smaller triangle right side measure is 5. This means the scale factor is

`p = kx`

`10 = 5x`

`x = 2`

So our scale factor is 2.

The second option is the answer.
