To decide if given figures will tessellate, we first look at the shapes' _____________________.

• number of sides

• interior angles

• number of vertices

• size

This figure can always be used to tessellate, because its sum of internal angles is 360°.

• Triangle

• Quadrilateral

• Pentagon

• Hexagon
