The little maid's papa has taken two
different-sized rectangular pieces of cardboard, and has clipped off a
triangular piece from one of them, so that when it is suspended by a
thread from the point A it hangs with the long side perfectly
horizontal, as shown in the illustration.
He has perplexed the child by
asking her to find the point A on the other card, so as to produce a
similar result when cut and suspended by a thread.
Of course, the
point must not be found
by trial clippings.
A curious and pretty point is involved in this
setting of the puzzle.
Can you discover it?
