Jesus Fish Meaning Ichthys

What are some symbols derived from ancient Greek symbols?

I’m doing a project in my English class and I have to find 10 modern day symbols that were derived from Greek symbols. So far the only one I have found is “Ichthys” a fish. The beginning Christians used a fish that represented Jesus Christ but to hide the meaning because religion was forbidden back then but still to this day the fish represents Jesus Christ.

Please help!

Also, the sorority houses, in colleges use the greek alphabet. I never quite understood why…
