This is a particular case, but it is not necessarily true. If triangles STU and XYZ are similar, the corresponding sides are in the same proportion. So, there exists a number $k \in \mathbb{R}$ such that

$ST = kXY,\quad TU=kYZ,\quad SU=kXZ$

So, if $k=1$ , the corresponding sides are actually congruent, but it can be any other number. For example, if $k=2$ , triangle XYZ is exactly twice as large as triangle STU, but they are still similar.
