# Equivalent Symbol (≡)

The equivalent symbol is used in modular arithmetic to express “wrap-around” behavior. Typically, the symbol is used in an expression like this:

In plain language, this means the angle is equivalent to the angle . Conceptually the two directions expressed by the angles are the same, so it is convenient to have a notation that expresses that relationship.
