Formulas for Triangles and QuadrilateralsGeometry 9-1 Formulas for Triangles and Quadrilaterals
Parallelograms Important: the height, h, must be perpendicular to the base ***Not on the formula chart
Example Find the area of a parallelogram with b = 9 in. and h = 5 in.
Example A parallelogram has an area of 44 in2. If the height of the parallelogram is 5.5 in., what is the length of the base?
Triangles and TrapezoidsImportant: the height, h, must be perpendicular to the base
Example Find the area of a trapezoid in which b1 = 8 in., b2 = 5 in., and h = 6.2 in.
Example Find b2 of the trapezoid, in which A = 231 mm2.
Example Find the area of the triangle.
Rhombus and Kite ***Not on the formula chart
Example Find d2 of a kite in which d1 = 14 in. and A = 238 in2.
Example Find the area of the rhombus.
