Using the applet on the previous slide, determine the SIX properties of parallelograms

Only one pair of opposite sides congruent
Equiangular quadrilateral
Diagonals bisect each other
Both pairs of opposite sides are congruent
Both pairs of opposite angles are congruent
Equilateral quadrialteral
Both pairs of opposite sides are parallel
Diagonals are perpendicular.
A diagonal divides the parallelogram into two congruent triangles
Diagonals bisect its angles
Diagonals are congruent.
Only one pair of opposite sides parallel
Consecutive angles are supplementary
