On our last test, I noticed we had a hard time justifying our answers. So, i'm posting the the properties of the quadrilaterals.
Parallelogram
- opposite sides are equal
- consecutive angles are suplementary
- diagonals bisect each other
Rectangle
- opposite sides are equal
- opposite angles are right angles
- consecutive angles are suplementary
- diagonals are congruent
- diagonals bisect each other
Rhombus
- opposite sides are equal
- opposite angles are right angles
- consecutive angles are suplementary
- diagonals bisect each other
- diagonals bisect opposite angles
- diagonals are perpendicular to each other
Square
- opposite sides are equal
- opposite angles are right angles
- opposite angles are right angles
- consecutive angles are suplementary
- diagonals are congruentdiagonals bisect each other
- diagonals bisect opposite angles
- diagonals are perpendicular to each other
