3. Trapezoid A quadrilateral with ONE pair of Parallel sides. b 1 - base one b 2 - base two

4. Trapezoid This is also a trapezoid. The bases are going up and down. b 1 - base one b 2 - base two

5. Isosceles Trapezoid A trapezoid with congruent sides b 1 - base one b 2 - base two leg

6. Parallelogram A quadrilateral with TWO pairs of parallel sides

7. Rhombus A parallelogram with 4 congruent sides

8. Rectangle A parallelogram with 4 right angles

9. Square A parallelogram with 4 congruent sides and 4 right angles

10. 2 pairs of consecutive sides are congruent Kite

11. Paper Folding Fold the diagonals of each Parallelogram. Measure the angles of the parallelogram Measure the angles formed by the diagonals Measure the angles where the diagonals intersect Measure the diagonals Measure the diagonals from the vertex to the intersection
