Composite Solids

This my Canon Eos 7D. Cameras are used all over the world to capture images. This camera is a composite solid. It is made up of two geometric shapes. The camera body makes up a rectangular prism and the lens makes up a cylinder. These two shapes connect to form a composite solid. There are many other examples of this in the real world as well. Every house is just a collection of geometric shapes. Each room makes up a rectangular prism and the roof makes a pyramid.  

Regular Hexagon

The object shown above is a table. This table's surface is a regular hexagon. It is a regular polygon because it's a closed figure, has straight lines, and all sides and angles are congruent. I found this table in my living room. Shapes like this are seen all over the world in stop signs as well. All of the sides and angles are congruent withing a stop sign. In nature, we see regular hexagons made by bees. As bees make their honey, the honey comb forms regular hexagons. Regular polygons are seen all over and are shown in the shapes of the world.
