Explain why

1

• Explain why
• equilateral triangles,
• squares and
• regular hexagons
• will tessellate on their own, but other regular
  polygons will not.

2
Explain why squares and regular octagons will
tessellate together
3
How do you decide where to start in order to find
the missing angles?
4
How would you convince somebody that the exterior
angles of a polygon add up to 360?
5
What clues do you look for when solving this
geometrical problem? How do you decide where to
start? Is it possible to solve the problem in a
different way?
