ParallelogramsDefinition: Quadrilateral with two pairs of

opposite parallel sides. Properties:

Opposite angles are congruent Both pairs of opposite sides are congruent Diagonals bisect Sum of interior angles is 360 degrees Consecutive angles are supplementaryOne pair of opposite sides are parallel and

congruent

Parallelograms (continued)Examples of Properties

Opposite angles are congruent

Opposite sides congruent and parallel

Diagonals bisect

RectanglesDefinition: A parallelogram with 4 right anglesProperties:

All properties that a parallelogram hasAll four angles are 90 degreesAll diagonals are congruent

Rectangles (continued)Examples of Properties

Opposite angles are congruent and 90 degrees

Diagonals bisect & congruent

Opposite sides congruent and parallel

RhombusDefinition: A parallelogram with 4 congruent

sidesProperties:

All properties that a parallelogram hasAll sides are congruentDiagonals are perpendicularDiagonals bisect the angles

Rhombus (continued)Examples of properties

Angles are bisected by the diagonals

All sides congruent and opposite sides parallel

Diagonals congruent & perpendicular bisector

of each other

SquaresDefinition: Parallelogram with 4 right angles

and 4 congruent sidesProperties:

All properties that a parallelogram has 4 right angles4 congruent sides Diagonals are congruent Diagonals are perpendicularDiagonals bisect the angles

Squares (continued)

Diagonals congruent & perpendicular bisector

of each other

Angles are bisected by the diagonals

All sides congruent and opposite sides parallel

Examples of properties

TrapezoidsDefinition: A quadrilateral with exactly one

pair of opposite, parallel sides.Properties:

Sum of all interior angles are 360 degreesExactly one pair of opposite, parallel sides

Trapezoids (continued)Examples of properties

Exactly one pair of opposite, parallel sides

KitesDefinition: A quadrilateral with exactly 2 pairs

of adjacent and congruent sidesProperties:

2 pairs of congruent and adjacent sidesDiagonals are perpendicularSum of interior angles is 360 degrees

Kites (continued)Examples of properties

Two pairs of adjacent, congruent sides

Diagonals are perpendicular
