```									    To summarize the Trapezoid Family:
• All trapezoids have exactly one pair of opposite sides
parallel
• The parallel sides are called the bases
• The non-parallel sides are called the legs
• Trapezoids have IASSOTS on the left and right sides
In addition, an isosceles trapezoid:
• has vertical symmetry
• So, the legs are congruent
• Base angles are congruent
• And diagonals are congruent
• Opposite angles are also supplementary
To summarize the Kite Family:
• All kites have exactly one symmetry
diagonal
• The symmetry diagonal bisects the angles
it connects
• The diagonals of a kite are perpendicular
In addition, a special kite:
• has congruent diagonals
To summarize the Parallelogram Family:
• A parallelogram has no symmetry
• Both pairs of opposite sides are parallel
• A diagonal separates the parallelogram into two
congruent triangles
• Both pairs of opposite sides are congruent
• Both pairs of opposite angles are congruent
• All pairs of consecutive angles are
supplementary
• The diagonals bisect each other
To summarize the Rhombus Family:
Because it is a parallelogram,
• Both pairs of opposite sides are parallel
• Both pairs of opposite angles are congruent
• All pair of consecutive angles are supplementary
• The diagonals bisect each other
In addition . . .
• All four sides are congruent so it is equilateral
• It has two symmetry diagonals so either
diagonals bisects the angles it connects
• The diagonals are perpendicular
To summarize the Rectangle Family:
Because it is a parallelogram:
• Both pairs of opposite sides are parallel
• Both pairs of opposite sides are congruent
• The diagonals bisect each other
In addition . . .

• A rectangle has two symmetry lines
• It has four right angles so it is equiangular
• The diagonals of a rectangle are congruent
The square has it all !!
Because it is a parallelogram. . .
• Both pairs of opposite sides are parallel
• The diagonals bisect each other
Because it is a rectangle . . .

• It is equiangular
• Any two angles are supplementary
• The diagonals are congruent
Because it is a rhombus . . .

• It is equilateral
• The diagonals are perpendicular
• The diagonals bisect the angles they connect
