Vocabulary • Quadrilateral – Any four sided polygon • Examples: Trapezoid, Parallelogram, Rectangle, Rhombus, Square
Quadrilaterals Parallelograms Trapezoids A four sided polygon in which both pairs of opposite sides are parallel. A quadrilateral that has one pair of opposite sides that are parallel Rhombus Rectangle A parallelogram that has 4 congruent sides. A parallelogram that has 4 right angles. Square A parallelogram with 4 right angles and 4 congruent sides.

A trapezoid has only one set of parallel sides. False A rectangle is a polygon with 4 sides which makes it a quadrilateral. True Try #4-10 on your own…raise your hand when you are done so you can start your homework assignment.
