QUADRILATERAL FLOWCHART

PARALLELOGRAM

Definition: quadrilateral with two pairs of parallel sides

Symmetry: 180º rotational symmetry at the intersection of the diagonals

Properties:

 opposite sides are congruent (same length)

 opposite angles are congruent (same measure)

 diagonals bisect each other

RHOMBUS

RECTANGLE

Definition: quadrilateral with 4 right angles

Definition: quadrilateral with 4 congruent sides

Symmetry: 180º rotational symmetry at the

intersection of the diagonals, and 2 lines of

intersection of the diagonals, and the diagonals

symmetry (thru midpoints of opposite sides)

are the lines of symmetry

Properties:

 opposite sides are parallel

 opposite sides are congruent (same length)

 opposite angles are congruent (same measure)

 diagonals bisect each other

 diagonals are congruent

 diagonals are perpendicular, , to each other

 diagonals bisect the angles

SQUARE

Definition: quadrilateral with 4 congruent sides and 4 right angles

Symmetry: 90º, 180º, 270º rotational symmetry at the intersection of the diagonals,

and 4 lines of symmetry (both diagonals and 2 lines thru midpoints of opposite sides)

Properties:

 opposite sides are parallel

 diagonals are congruent

 diagonals bisect each other

 diagonals are perpendicular, , to each other

 diagonals bisect the angles
