# Properties of a Rhombus

This quadrilateral has some special properties already: Segments AF, FE, and BE are all exactly 5 units long, but you can adjust the length of segment AB. Notice, in the algebra menu, that the slopes for each line are also given as m, m1, m2, and m3. What happens to the slopes of the lines when you drag each of the points around in order to make line AB exactly 5 units long?
