GEOMETRY EOC
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 Rectangle
Rectangles are types of parallelograms.
Opposite sides are parallel and congruent.
The diagonals bisect.
The diagonals’ central angles are congruent.
The diagonals are congruent.
All vertices are right angles.

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.

Properties of a Trapezoid
A trapezoid has 1 pair of parellel sides
 Adjacent angles are supplementary
 Diagonals are congruent
 A trapezoid can be divided into four
triangles


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.
