In this lesson, you used deductive reasoning to prove conjectures about quadrilaterals.

Attributes of each type of quadrilateral, including parallelograms, rectangles, kites, and trapezoids, are important to consider when using deductive reasoning. However, you must also pay attention to how statements are linked together, making sure that they are linked in a logical manner.

Consider the flow proof below.

Given isosceles trapezoid *WXYZ*, show that Δ*WXP* ∼ Δ*YZP*.

In this flow proof, the first two steps must be stated first so that the final step may be concluded from the information contained in each step.
