Parallelogram

Opposite angles are equal.
 Consecutive angles are supplementary.
 Opposite sides are congruent.
 Any side can be considered a base.
 The altitude is the perpendicular
distance from the base to the opposite
side.
 The diagonals bisect.

Properties of a Rhombus
All sides are the same length.
 Sides across from each other are
parellel.
 No angles are 90 degrees
 Any two angles positioned next to each
other are 90 degrees when added.



The bases (top & bottom) of an isosceles
trapezoid are parallel.
Opposite sides of an isosceles trapezoid
are the same length (congruent)
The angles on either side of the bases are
the same size/measure(congruent)
The diagonals are congruent
Adjacent angles (next to each other) along
the sides are supplementary. That means
their measures adds up to 180 degrees.
