A quadrilateral is a polygon with four sides. It is much more complicated than a triangle. However, you can explore dynamic quadrilaterals the same ways you explored dynamic triangles. You can construct dynamic quadrilaterals the same ways you constructed dynamic triangles.[br][br]Chat about the constraints that have been constructed into these quadrilaterals.[br]Can you figure out how they were constructed? Try to construct them and test them by dragging.
1. Drag each vertex of each quadrilateral. Can you tell what constraints each of these[br]quadrilaterals was constructed with? (For example, one of them is built in such a way that it will always be a kite. Which one is it?) What are some of the other constraints on the other polys?
2. Which of these quadrilaterals can be dynamically dragged to match which other ones? For example, can poly1 match all the others?[br]
3. Check your answers by constructing the different polygons with the dependencies that you think they have.[br]
