Theorems & Postulates
area addition postulate 
the area of a region is equal to the sum of the areas of its nonoverlapping parts 
Formulas
area of a parallelogram 
area = bh 
area of a triangle 
area = 1/2bh 
area of a trapezoid 
area = [(b1 + b2)h]/2 
area of a rhombus or kite

volume = base * height 
volume of a rectangular prism 
volume = length width height 
volume of a cube 
volume = edge length^{3} 
volume of a cylinder 
volume = area of the base * height
