It seems like solutions to geometry problems always involve right angles:

Thanks to WolframAlpha, you can easily compute a wealth of nutritional information based on your Thanksgiving intake!
This hypothetical 1129-calorie dinner plate above is not intended to be an accurate representation of my typical Thanksgiving meal. Indeed, this is not even an accurate representation of my first serving at a typical Thanksgiving dinner. These hypothetical portions are meant to be used for educational purposes only.
An example of tiling the plane with regular hexagons. Well, maybe not the whole plane, but you get the idea.
A valid tiling of the plane means that everything fits together perfectly–no gaps.
A nice simple little exercise is trying to figure out which regular polygons can be used to tile the plane like this. The next step is to allow the use of more than one kind of regular pentagon, and so on.
