The sides of a triangle are in the ratio of 2: 3: 4. if the measure of the shortest side of the triangle is 12 centimeters, what is the length of the longest side?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
