Answer :
Nothing could be easier than the solution of this
puzzle—when you know how to do it.
And yet it is apt to
perplex the novice a good deal if he wants to do it in the fewest
possible pieces—three.
All you have to do is to find the
point A, midway between B and C, and then cut from A to D and from A to
E.
The three pieces then form a square in the manner shown.
Of course,
the proportions of the original figure must be correct; thus the
triangle BEF is just a quarter of the square BCDF.
Draw lines from B to
D and from C to F and this will be clear.
