6 + 6 = 12 ©

You cannot make a ball using only hexagons ©

hexagons stay flat ©

but 20 hexagons ©

and 12 pentagons ©

make a football ©

Can you find a hexagon in this flys eye ©

Now find a pentagon ©

Find a hexagon on this tortoise shell ©

Now find a pentagon ©

Without pentagons the shell would be flat ©
