1. SPECIAL QUADRILATERALS
Aren’t you SUPER excited?

2. PARALLELOGRAM
Definition: A quadrilateral with opposite sides are parallel.
Properties:
Opposite sides are congruent
Opposite angles are congruent
Consecutive angles are supplementary
Diagonals bisect each other.

3. RHOMBUS Definition: Parallelogram with 4 congruent sides PROPERTIES
ALL of the properties of a parallelogram
Each diagonal bisect a pair of opposite angles
Diagonals are perpendicular

4. RECTANGLE
Definition: A parallelogram with four congruent angles. (90 degrees)
PROPERTIES
ALL of the properties of a parallelogram
Diagonals are congruent.

5. SQUARE
Definition: A equiangular and equilateral parallelogram. (In other words it is a rhombus and a rectangle)
PROPERTIES:
All of the properties of a rhombus.
All of the properties of a rectangle.

6. Got all that??? Lets see! Number a clean half sheet of paper 1-11
I will show you a characteristic of a special quadrilateral. Tell what special quadrilateral it is.
Use P for parallelogram, H for rhombus, R for rectangle and S for square. “None of these” for none of these.
Several properties will have more than one answer.

7. Here we go!! Opposite sides parallel. 4 right angles 4 congruent sides
Diagonals perpendicular
Opposite angles congruent
Four congruent sides and four congruent angles

8. Not done yet Diagonals bisect opposite angles Opposite sides congruent
Consecutive sides parallel
Four congruent angles
Diagonals congruent
NOW TRADE PAPERS.

11. Mini Quiz: No Notes Use P for Parallelogram Use H for Rhombus
Use R for Rectangle
Use S for Square
Use NONE for none of these.
Keep in mind, most of these will have more than one answer.

12. Give the figure(s) that have the following characteristics
Diagonals are perpendicular

All angles are right
Is Equilateral
Opposite sides are parallel.

13. Almost done Diagonals are congruent. Is equiangular
Consecutive angles are supplementary
Interior angles have a sum of 9000 degrees
Is both equiangular and equilateral.
