Area Of Triangles and Parallelograms.
Theorem:
The area of a parallelogram is equal to the product of it base
and
height.( A = bh)
Theorem:
The area of a triangle is the product of half the length of its
base and
the length of the height.
Corollary:
The area of a rhombus equals half the product of its diagonals.
( A = ½ d1 d2 )
Theorem: The Area of Trapezoids:
The area of a trapezoid is equal to the product of half its
height and
the sum of bases.
( A = ½ h( b1 + b2 ))
