Exploring Quadrilaterals: Sides Angles, and Diagonals

Exploring Quadrilaterals: Sides, Angles, and Diagonals

Several types of quadrilaterals and their diagonals have been constructed in the sketch below Use the buttons to make figures appear. Figures will overlap, use the hide button to hide an obstructing figure.
(Note: The sketch below requires a Java-enabled browser. You can access the real sketch here and use The Geometer's Sketchpad to open it. Sketchpad is available from Key Curriculum Press).

Use the buttons to display/hide the figures (one is already showing)
Drag the RED points around to determine the behavior and attributes of the figure and its diagonals

Figure	Diagonals Bisect? Always?	Diagonals Perpendicular? Always?	Diagonals Equal? Always?	Diagonals form congruent triangles? How Many if so?

After completing the activities above you should have a fair idea of how these quadrilaterals compare with one another.
