TO DRAW A SQUARE, GIVEN IN MAGNITUDE, WITHIN A LARGER SQUARE GIVEN IN
POSITION AND MAGNITUDE; THE SIDES OF THE TWO SQUARES BEING PARALLEL.
[Illustration: Fig. 34.]
Let _AB_, Fig. 34., be the sight-magnitude of the side of the smaller
square, and _AC_ that of the side of the larger square.
Draw the larger square. Let _DEFG_ be the square so drawn.
Join _EG_ and _DF_.
On either _DE_ or _DG_ set off, in perspective ratio, _DH_ equal to
one half of _BC_. Through _H_ draw _HK_ to the vanishing-point of
_DE_, cutting _DF_ in _I_ and _EG_ in _K_. Through _I_ and _K_ draw
_IM_, _KL_, to vanishing-point of _DG_, cutting _DF_ in _L_ and _EG_
in _M_. Join _LM_.
