In the process of creating the mathematics references and classrooms we put together a substantial collection of image files. Some of these are of specific objects (regular hexagons, 30° angles, etc.) while the others are specific mathematical symbols (congruence, the empty set, etc.). We've put together several collections of these images and made them available under the Creative Commons Attribution license (version 2.5).
| Name | Files | Description |
| Geometry Images | downloadpreview | These images include standard geometry concepts (e.g. right triangles and segment relationships) and symbols (e.g. congruence and similarity). The symbols correspond roughly to a 12 point font. |
| Algebra Images | downloadpreview | Algebra, at the high school level, doesn't use a lot of unique symbols. This set consists primarily of items used in set theory (e.g. intersection and union). The symbols correspond roughly to a 12 point font. |
