The =E2=80=98congruent to=E2=80=99 symbol ( &cong; or &#8773; ): =E2=80=98=
=E2=89=85=E2=80=99  * means, generally, to have the same shape (and size), =
while =E2=80=98~=E2=80=99 (the =E2=80=98similar to=E2=80=99 symbol) means t=
o have the same shape (i.e., =E2=80=98congruent following scaling=E2=80=99)=
.  They both imply that rotation, reflection and translation are irrelevant=
.=20

=20

Does anyone know of any standardized symbology to mean =E2=80=98congruent v=
ia reflection=E2=80=99, or =E2=80=98similar via  rotation=E2=80=99?=20

=20

I=E2=80=99m aware that the Noun project has putzed around some with symbols=
 for certain things of a quasi-topological nature, but don=E2=80=99t know o=
f forays in this direction.

Cheers
