In Tessellations: The math of Tiling post, we have learned that over there are just three continuous polygons that deserve to tessellate the plane: squares, it is intended triangles, and regular hexagons. In Figure 1, we can see why this is so. The angle sum of the internal angles of the consistent polygons conference at a point add up to 360 degrees.
You are watching: Which regular polygon can be used to form a tessellation
Figure 1 – Tessellating regular polygons.
Looking at the other constant polygons as displayed in figure 2, we have the right to see clearly why the polygons can not tessellate. The sums that the inner angles are either greater than or less than 360 degrees.
Figure 2 – Non-tessellating constant polygons.
In this post, we are going to present algebraically that there are only 3 continual tessellations. Us will usage the notation
In the proof, as shown in figure 1, we are going to display that the product of the measure up of the internal angle that a consistent polygon multiplied by the variety of vertices conference at a point is equal to 360 degrees.
Theorem: There are only three constant tessellations: it is intended triangles, squares, and also regular hexagons.
