Geometric properties of the Taj Mahal

[Amazing]

Alright, so I'm working on my Pre-AP Geometry project that's due tomorrow and I need to find 30 geometric properties and label them on my poster... I have 22 but can't think of any others and I would really appreciate it if you guys could post some to help me finish this up so I can start practicing my presentation. By geometric properties I mean things like symmetry (obviously the entire Taj Mahal has perfect vertical symmetry), parallel lines, reflections, dilations, all things having to do with geometry, but not like measurements... He wants geometric properties. We're allowed to have measurements and shapes, but he said to try not to have a lot.

So just shoot as much as you can at me please!
