Area of Quadrilateralsby Jake Aronson, Ryan Listro, and Fred GussParallelograms:SquaresRectanglesRhombusOther: KitesTrapezoidsWhat is a quadrilateral?A quadrilateral is a four-sided plane.What is a parallelogram?
• 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
• What figures are parallelograms?
• Squares
• Rectangles
• Rhombuses
• Area of a Parallelogram
• Theorem 6.21:
• The area of a parallelogram is the product of base and its corresponding height.
• 4 8A=(8)(4)>>>>>>What other figures are quadrilaterals?
• Kites
• Trapezoids
• 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.
• Area of a Square and RectangleA=424A=(4)(8)484Trapezoid:
• Area=1/2(Height)(Base1+Base2)
• Rhombus and Kite:
• 1/2(Diagonal1xDiagonal2)
• Area of a Trapezoid, Rhombus, and Kite42A=(1/2)(2x4)3A=(1/2)(3)(2+4)42Helpful Hints
• Area of a Square…
• Area of a SQUARE=SideSQUARED
• Area of a Kite…
• Please DaD:(1/2)Product of DandD--(1/2)DaDExamples-SquareThe length of one of the sides is 3. What is the area of the square?9 units 2Examples-RectangleThe length of one of the sides is 4, and the other is 6. What is the area of the rectangle?24 units 2Examples-KiteThe length of one of the diagonals is 5, and the other is 8. What is the area of the kite?20 units 2Examples-RectangleThe height of the building is 350 feet and the width is 20 feet. What is the area of the building?7,000 feet 2Examples-RhombusThe length of one of the diagonals is 16, and the other is 8. What is the area of the rhombus?64 units 2Examples-TrapezoidThe length of one of the bases is 2, and the other is 4. The height is 8. What is the area of the trapezoid?24 units 2THE END
