The steps to construct a line perpendicular to $$XY$$ and passing through $$P$$ is given in random order :
$$1.$$ Move the set square along XY so the other short side touches Point P.
$$2.$$ Use the edge of the set square to draw a line through Point P.
$$3.$$ Draw a line $$XY$$ and mark point $$P$$.
