Tessellations in a Table

I saw a table and noticed it had tessellations in it. First off, the shapes are hexagons. This can be proved using the formula (n-2)180 where n is the number of sides and the sum should be the sum of the angles. So (6-2)180= 720 degrees.

The hexagons fit together at the intersections because the two smaller angles are about 50 degrees and the two larger angles are about 130 degrees.  Altogether it is 360 degrees.  This means there are no gaps in the tessellation, and it fits together well.  (~NW5)
