Thread: Geometry project

I am doing a project for my Geometry class, and I am making a powerpoint with proofs for Euclid's first book propostions, to be more specific, the propositions related to triangles. I would like some ideas of a more "hands on" visual for this? I was thinking using Kinex to demonstrate them, but that is pretty boring and I lack creativity. Any help would be wonderful!

use one of the support towers of the Golden Gate Bridge..
at least lots of nice pics to look at and lots of triangles
