I am working on a geometry problem where I have to build a mobile of the quad. family. I have to state the properties of each figure. For a parallelogram I have 1. opp. sides are congruent 2. opp. angles are congruent 3. diagonals bisect each other and are congruent. For a rhombus I have 1. each diagonal bisects and are perpendicular. For a trapezoid I have the midsegment half the length of the base.
I have nothing for a rectangle, square, kite or isosceles trapezoid.
My question is are the ones I have correct and can you help me with the properties I don't have

For a parallelogram, add:
 opposites sides are parallel
For a rhombus, add:
all the properties of a parallelogram, plus
 diagonals are angle bisectors
 ______ axes of symmetry
For a trapezoid, add:
 ____ pair of parallel opposite sides
For a rectangle, add:
all the properties of a parallelogram, plus
 _________ sides are perpendicular to each other
 ___ axes of symmetry
For a square, add:
all the properties of a rectangle, plu
 all sides are congruent
 ____ axes of symmetry
For a kite:
 has ____ pairs of congruent adjacent sides.
 Diagonals are perpendicular to each other
 ____ of the diagonals is an axis of symmetry, therefore it bisects the internal angles.
For an isoceles trapezoid,
 _____ pair of opposite parallel sides
 _____ axis of symmetry
