triangle on the right. What rule did Paloma apply to make the new triangle?

Answer 1

Dilation with scale factor 1/2 = 0.5

Answer 2

Answer: Dilation with scale factor 1/2 = 0.5

===========================================

Step-by-step explanation:

The image is not the same size as the preimage. This means a dilation has occurred. Specifically, the image has been shrunk. The scale factor k must be in the interval 0 < k < 1.

-----------

Point B is at (2,2)

It then moves to (1,1)

The scale factor is 1/2 = 0.5

To find the scale factor, you divide the image x coordinate over the preimage x coordinate.

So the triangle is now half as tall and wide compared to from before.

Point A is the center of dilation. The origin is often the default center. The center of dilation is the only point that doesn't move (fixed point).
