Problem Statement
Prove that for any convex quadrilateral it is always possible to cut out three smaller
quadrilaterals similar to the original one with the scale factor equal to 1/2. (The
angles of a smaller quadrilateral are equal to the corresponding original angles and
the sides are twice smaller then the corresponding sides of the original quadrilateral.)
