If the scaling factor from one similar triangle to another is k, how do the corresponding sides compare?

Scaling a figure by factor k means every length is multiplied by k. For two similar triangles connected by that scale, each side length in the second triangle is k times the corresponding side length in the first. So the corresponding sides are multiplied by k. If k > 1 the second triangle is larger; if 0 < k < 1 it’s smaller. (Area would scale by k^2, since area depends on length squared.)
