ANSWER:
They are not similar.
STEP-BY-STEP EXPLANATION:
We have 2 figures ABCD and JKLM, they are 4-sided figures.
These figures are not similar, since one is square and the other is a rectangle.
No transformation changes the proportion of the figure, even if it is larger or smaller, the proportion must be maintained.
therefore, we determine that these two figures are not similar.
