Special Quadrilaterals - Trapezoids, Isosceles Trapezoids, and Kites

Description
The interactive applet above contains trapezoid ABDC, isosceles trapezoid GG'F'F, and kite MJLH. Use each of their moveable points to form conclusions about what you believe the rules are for each. Try to be as descriptive about the following possible characteristics (if the part is included or relevant):[br]-Diagonal length[br]-Diagonal intersection angle[br]-Consecutive angle measurements[br]-Opposite angle measurements[br]-Consecutive side lengths[br]-Opposite side lengths[br]-Slopes of sides
Trapezoid (See shape ABDC)
What seem to be the special properties for a trapezoid, based on your observation? What indicates that to you? Be specific and include as much information as possible.
Isosceles Trapezoid (See shape GG'F'F)
What seem to be the special properties for an isosceles trapezoid, based on your observation? What indicates that to you? Be specific and include as much information as possible.
Kite (See shape MJLH)
What seem to be the special properties for a kite, based on your observation? What indicates that to you? Be specific and include as much information as possible.
