Question

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.

A. The triangle pre-image is closer to the point of dilation than the image.
B. The triangle image is closer to the point of dilation than the pre-image.
C. The value of the scale factor, , is between 0 and 1.
D. The value of the scale factor, 6, is greater than 1.
E. The vertices of the pre-image are collinear with the vertices of the image.

Answer 1

A. The triangle pre-image is closer to the point of dilation than the image.
D. The value of the scale factor, 6, is greater than 1.

Answer 2

A, and D, for sure.
although E I have no idea what those words mean (XD)

However B and C are completely wrong.

" S " is the "pre-image" and " S' " is the "Image"
the pre-image is closer to the dilation point P in distance 2 units, whilst the other is 12 units away.
