In modern mathematics, symmetries are usually encoded by groupoids; one also often upgrades groups to more structured objects such as

The fact that every tranformation can be written as a translation and then a rotation or a reflection and then a rotation is a really cool result that introduces key ideas which you could easily think about in early highschool (and again suggests more advanced topics like groupoids).
