What is the symbol to denote that two triangles are similar?

Question

Does there exist a unique symbol to denote that two triangles are similar to each other without resorting to using the phrase "is similar"?

Answer 1

$\triangle ABC \sim \triangle DEF$.

Answer 2

The symbol for denoting similar triangles is ($\color{blue}{\sim}$)

Notice, suppose $\triangle ABC$ & $\triangle PQR$ are similar then in LaTex it is written as $\text{"\triangle ABC \sim \triangle PQR"}$ surrounded in-between by 2 or 4 dollar signs which appears as follows $$\color{blue}{\triangle ABC \sim \triangle PQR}$$
