2. Types of Quadrilaterals
Parallelogram
Rectangle
Rhombus
Square
Kite
Trapezoid
Isosceles Trapezoid

3. Parallelogram Opposite sides parallel Opposite sides equal in length
Opposite angles equal
Diagonals bisect each other

4. Rectangle Opposite sides parallel Opposite sides equal in length
All angles right angles
Diagonals congruent and bisect each other

5. Rhombus Opposite sides parallel All sides equal in length
Opposite angles equal
Diagonals are perpendicular bisectors and bisect angles

6. Square Opposite sides parallel All sides equal in length
All angles right angles
Diagonals congruent
Diagonals perpendicular bisectors and bisect angles

7. Kite Each set of adjacent sides equal in length
Opposite angles equal where pairs meet
Diagonals are perpendicular bisectors

8. Trapezoid
Only one pair of opposite sides parallel

9. Isosceles Trapezoid Opposite sides parallel
Non-parallel sides equal in length
Both sets of base angles equal
Diagonals congruent

10. Trapeziums
No parallel sides
The End.
