===Group 4: Create a Trapezoid. Prove that it is a Trapezoid and that a line connecting the midpoints of the non-parallel sides is parallel to the other two sides. ===



1) Create a trapezoid similar to ABCD (AB and CD must be parallel) 2) Find the slope of AB and CD to verify that they are parallel 3) Find the midpoint of AD and BC 4) Create a line segment that connects the two midpoints 5) Find the slope of the line segment between the midpoints to verify that it is parallel to AB and CD (all three slopes should be the same)
