Math Quadrilaterals

kite:
 definiton: no parellel sides one opp. angles = 2 sets of = sides
 properties:
 diagonals that are perpendicular 90 angles
 1 set opp. angles =

isosceles trapezoid:
 definition: one pare parellel sides legs are =
 properties:
 legs are =
 diagonals =
 bases angles are=
 adj. angles = 180

trapezoids:
 definition: one pair of paralell sides and opp. sides are not =
 midsegment 
 connects the midpoints of the legs
 formula M=1/2 (b1+b2)

Square:
 definition: 4 right angles and 4 = sides
 properties:
 all 90 angles
 4 = sides
 opp. sides = and parallel
 diagonals perpendicular
 diagonals =
 adj.angles = 180
 4 isosceles triangles
 diagonals bisect opp. angles

Rectangle:
 definition: oposite sides that are = and paralle four 90 angles
 properties:
 adj.angles = 180
 all 90 angles
 diagonals are =
 diagonals make 4 isosceles triangles

Rhombus:
 definition: parallelogram with 4 equal sides
 properties of rhombi:
 opp. angles are equal
 adjacent angles equal 180
 diagonals are perpinduculal
 diagonals bisect opp. angles

Parallelogram:
deff.Opposite sides are parallel and equal
 properties:
 opposite angles are equal
 adjcent angles add to 180
 diagonals bisect
