A quadrilateral is a four-sided plane.

3
A parallelogram is a four-sided plane that meets the following criteria: Opposite sides are parallel Opposite sides are congruent Opposite angles are congruent Consecutive angles are supplementary Diagonals bisect each other

4
Squares Rectangles Rhombuses

5
Theorem 6.21: The area of a parallelogram is the product of base and its corresponding height. 4 8 A=(8)(4) > > >>

6
Kites Trapezoids

7
Postulate 22: The area of a square is the square of the length of one of its sides. Theorem 6.20: The area of a rectangle is the product of its base and height. 4 4 A= A=(4)(8)

8
Trapezoid: Area=1/2(Height)(Base 1 +Base 2 ) Rhombus and Kite: 1/2(Diagonal 1 xDiagonal 2 ) 4 2 A=(1/2)(3)(2+4) A=(1/2)(2x4)
