### Parallelogram

-quadrilateral

-2 pairs opp parallel sides

-2 pairs opp congruent angles

-2 pairs opp congruent sides

-consecutive angles are supp

-diagonals bisect each other

### rectangle

-parallelogram with 4 congruent angles, 4 right angles (equiangular)

-all properties of a parallelogram apply

-diagonals are congruent

### rhombus

-parallelogram with 4 congruent sides (equilateral)

-all properties of a parallelogram apply

-diagonals are perpendicular

-diagonals bisect the angles

### square

-parallelogram with 4 congruent sides and angles (equilateral, equiangular= regular)

-both rectangle and rhombus

-all properties of a parallelogram, rhombus, and rectangle apply

### kite

-quadrilateral with no parallel sides but two pairs of adjacent congruent sides (opp sides are not congruent)

-diagonals are perpendicular

-only 1 pair of opp angles are congruent (between non-congruent sides)

-other 2 angles are bisected by diagonal

### trapezoid

-quadrilateral with 1 pair of parallel sides

-parallel sides are bases

-non parallel sides are legs

-midsegment (median) joins the midpoints of the legs and is parallel to both bases (avg of the bases)

-midsegment=1/2 (b1+b2)
