Parts of a Parallelogram  Key Points:  A base of a parallelogram can be any one of its sides.  An altitude is perpendicular to a base and is drawn from the side opposite the base.  The height is the length of the altitude.

What do you notice?

Example 1: Find the area of each parallelogram. A=bh A=5(4) A=20 A=bh A=2(3.5) A=7

A=bh A=13(9) A=117

P A=1/2 bh A=1/2 (13)(12) A=78

Find the area of the composite figure. 4 A=1/2 bh=(1/2)(3)(4) =6 A=bh=4(6)=24 =(1/2)(3)(4) Total Area = =36
