the fact of being alike
The fact that two or more people or things are like each other in some way.
用法パターン：
a similarity between [things]
よくある間違い：
Learners often confuse "similar" (adjective) and "similarity" (noun). For example, they may say *"There is similar between the two"* instead of "There is a similarity between the two" or "They are similar." Another common mistake is using the wrong preposition: "similarity of A and B" is less natural than "similarity between A and B" in most contexts.

shape-preserving geometric transformation
In math, a special change to a shape that keeps its form the same but can make it bigger, smaller, or moved.
用法パターン：
a similarity transformation of [a figure/matrix]
よくある間違い：
Learners may confuse the everyday meaning of "similarity" (things being alike) with the technical mathematical sense. In geometry, "similarity" refers to a specific type of transformation or a formal relation between objects, not just a loose resemblance.
類義語
similarity transformation (Full technical term; more specific than the shorter "similarity" when context is not clear.)
対義語
distortion (A transformation that changes the shape in a non‑uniform way, opposite of similarity in geometry.)
