Properties of Quadrilaterals
Move points B, C, and D (not A) to form different quadrilaterals. When you create a quadrilateral, its name will appear on the righthand side.
*Do not cross points.
**Do not drag points below the x=axis.
***Do not make concave polygons. This program only works with convex polygons!
Record the properties of each quadrilateral as you form them.
