alter a letter

changing a letter = move a space
(to create an edge)

bag, big and bog form an equilateral triangle

what happens if you then include beg?

and then bug?

can you think of a way to create a square?

how could a rhombus (60, 120) be described by
bag, bay, boy and bog?
can you think of another way?

what shape is big, bug, bag, but, bat, bit?

what shape is bat, bet, bit, bot and but?

this task was suggested by Gordon Haigh when he was at Wolverhampton University
