Quadrilateral Trapezoid Isosceles Trapezoid Parallelogram RhombusRectangle Quadrilateral Tree Kite Square

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

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

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

Parallelogram A quadrilateral with TWO pairs of parallel sides

Rhombus A parallelogram with 4 congruent sides

Rectangle A parallelogram with 4 right angles

Square A parallelogram with 4 congruent sides and 4 right angles

2 pairs of consecutive sides are congruent Kite
