You can see that coopies of a shape fits together without any gaps to make a tessellation.

In any tessellations, the sum of the angles at the point where the vertices of the shapes meet is 360 degree. Keep it in your mind that id there are gaps between the shapes that fits together or if the sum of angles won't be 360 degree, it means that is not tessellating shapes.
