Suppose is a quadrilateral and the diagonal

*lies on*

*and diagonal*

*lies on*

*. Assume the diagonals intersect at point*

*.*

Without graphing, what is the relationship between the diagonals? How do you know?

Examine each line's slope to determine the relationship between the two lines.

Graph the lines on graph paper. If

is a midpoint of, what type of quadrilateral couldbe? Is there more than one possible type? Explain how you know.The diagonals are perpendicular. At least one of the diagonals is bisected.
