Which statements justify that the dilation of triangle stu is an enlargement increasing its size by the magnitude of the scale factor? check all that apply. the triangle pre-image is closer to the point of dilation than the image. the triangle image is closer to the point of dilation than the pre-image. the value of the scale factor, , is between 0 and 1. the value of the scale factor, 6, is greater than 1. the vertices of the pre-image are collinear with the vertices of the image.

i'm pretty sure its c & e

step-by-step explanation:

Scale factor is the ratio of the distance of centre of dilation to the image divided by that to the preimage.   therefore:
a dilation is a magnification if the scale factor is greater than one.
it is a shrinking if the scale factor is less than one.
if the scale factor is exactly one, then the image coincides with the preimage.

the triangle pre-image is closer to the point of dilation than the image.
[so the image distance is farther than the preimage   => image is bigger, so magnification]
the triangle image is closer to the point of dilation than the pre-image.
[ image is closer to point of dilation, so smaller => shrinking ]
the value of the scale factor, , is between 0 and 1.
[ scale factor < 1   => shrinking ]
the value of the scale factor, 6, is greater than 1.
[ scale factor > 1 => magnification ]
the vertices of the pre-image are collinear with the vertices of the image.
[ the line of collinearity is not defined, so statement is meaningless. ]
