A cornucopia of quadrilaterals
by Alsina, Claudi, Nelsen, Roger B.
fromDolciani mathematical expositions
"A Cornucopia of Quadrilaterals collects and organizes hundreds of beautiful and surprising results about four-sided figures--for example, that the midpoints of the sides of any quadrilateral are the vertices of a parallelogram, or that in a convex quadrilateral (not a parallelo…
