Definition: Reflexive
A binary relation [math]R [/math] on a set [math]A [/math] is reflexive if for every [math]x \href{/cs2800/wiki/index.php/%E2%88%88}{∈} A [/math], [math]\href{/cs2800/wiki/index.php/XRy}{xRx} [/math].

In a picture, this means that every element of [math]A [/math] has a self-loop: an edge back to itself.
