Triangle abctriangle abc is transformed with the center of dilation at the origin. pre-image: △abc with vertices a(−5, −4), b(−7, 3), c(3, −2) image: △a′b′c′ with vertices a′(−3.75, −3), b′(−5.25, 2.25), c′(2.25, −1.5) what is the scale factor of the dilation that maps the pre-image to the image?

Pre Image  having vertices : △ABC with vertices A(−5, −4), B(−7, 3), C(3, −2)

Image having vertices : △A′B′C′ with vertices A′(−3.75, −3), B′(−5.25, 2.25), C′(2.25, −1.5).

As, Size of Preimage > Size of image

So, 0<Dilation Factor <1

When a triangle is dilated , the preimage and image are similar to each other .

Scale factor can be get through by finding the ratio of any of corresponding sides of triangle.

So, Scale Factor of Dilation =

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
