- What does $\cong$ sign represent? - Mathematics Stack Exchange
In geometry, $\cong$ means congruence of figures, which means the figures have the same shape and size (In advanced geometry, it means one is the image of the other under a mapping known as an "isometry", which provides a formal definition of what "same shape and size" means) Two congruent triangles look exactly the same, but they are not the
- Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange
$\cong$ is used to show a congruency between two mathematical expressions, which could be geometrical, topological, and when using modulo arithmetic you can get different numbers that are congruent, e g , $5 \text{ mod } 3 \cong 11 \text{ mod } 3$ (although this is also written as $\equiv$) In LaTeX it is coded as \cong
