Yes, there are but this browser is not any use for them. The following are a few examples:

There is a triangular shape (delta) for triangles,

there is a kind of "L" shape, but acute angled, to represent angles,

Oce represents circumference,

O with a dot in the middle represents a circle,

two forward slashes represent parallel,

three forward slashes represent congruent (rare),

there are superscripts form angle measures (degrees-minutes-seconds, or radians).
