The figures in a tessellation do not overlap or leave gaps. If the figures are polygons, the sum of the measures of the angles around any vertex in the tessellation must be 360.

Four identical trapezoids are connected, with short bases of the left two connected and long bases of the right two connected. The shared vertex has two 120 degree angles and two 60 degree angles.

Tessellation

Three identical pentagons are connected, with a gap between two at the shared vertex.

Not a tessellation
