3. Properties for Parallelograms
Both pairs of opposite sides are parallel and congruent
Diagonals bisect each other
Opposite angles are congruent
Consecutive angles are supplementary
DRAW A PARALLELOGRAM

4. Parallelogram B a E C D

5. Tests for Parallelograms
If one pair of opposite sides are parallel and congruent, then it is a parallelogram
If both pairs of opposite sides are parallel, then it is a parallelogram
If both pairs of opposite sides are congruent, then it is a parallelogram
If both pairs of opposite angles are congruent, then it is a parallelogram
If diagonals bisect each other, then it is a parallelogram

6. Properties of a Rectangle
Both pairs of opposite sides are parallel and congruent
Diagonals bisect each other
Opposite angles are congruent
Consecutive angles are supplementary
All four angles are right
Diagonals are congruent
DRAW A RECTANGLE

7. Rectangles: If <DAE = 30 degrees can you determine the remaining angles?B E D C

8. Tests for Rectangles
If a quadrilateral has four right angles, then it is a rectangle
If a parallelogram has congruent diagonals, then it is a rectangle

9. Properties for a Rhombus
Both pairs of opposite sides are parallel and congruent
Diagonals bisect each other
Opposite angles are congruent
Consecutive angles are supplementary
Diagonals intersect at 90 degree angles
Each diagonal bisects opposite angles
All sides are congruent

10. Rhombi: If <BAE = 25degrees can you determine the other angles?

11. Tests for Rhombi
If the diagonals of a parallelogram are perpendicular, then it is a rhombus

12. Properties of Squares
Both pairs of opposite sides are parallel and congruent
Diagonals bisect each other
Opposite angles are congruent
Consecutive angles are supplementary
All four angles are right
Diagonals are congruent
Diagonals intersect at 90 degree angles
Each diagonal bisects opposite angles
All sides are congruent

13. Squares A B A E D C

14. If a quadrilateral is a rectangle and a rhombus, then it is a square
Tests for Squares
If a quadrilateral is a rectangle and a rhombus, then it is a square

15. Trapezoids
