Discover Properties of a Trapezoid

Author:Kristin Massey

The applet below contains a quadrilateral that ALWAYS remains a trapezoid. The purpose of this applet is to help you understand many of the geometric properties a trapezoid has. Some of these properties are unique and only hold true for a trapezoid (and
