Slide 4: Rectangles
-A rectangle is a four-sided shape where every angle is a right angle -The distance from one corner of a rectangle to the opposite corner is called the diagonal -opposite sides are parallel and of equal length - Area = bh

Slide 8: Trapezoid
-The trapezoid is a quadrilateral with one pair of parallel sides -The height of the trapezoid is the perpendicular distance between the bases -Every trapezoid has two bases. -area = ((b1 + b2) / 2)h.
