Homework Help: geometry

Posted by josh on Saturday, December 12, 2009 at 7:44pm.

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

all the properties of a rectangle, plu
- all sides are congruent
- ____ axes of symmetry

For a kite:
- has ____ pairs of congruent adjacent sides.
