Quadrilateral Area Formulas in Plane Geometry
This page provides a comprehensive overview of area formulas for various quadrilaterals in plane geometry. It serves as an excellent resource for students learning how to calculate the area of figures and irregular surface areas.
The page begins with a rectangle, showing its formula as P = a · b, where 'a' and 'b' represent the lengths of its sides. This is followed by the parallelogram, which has two formulas: P = a · h basetimesheight and P = a · b · sinα productofsidesandsineoftheanglebetweenthem.
Next, the trapezoid formula is presented as P = (a+b)h/2, where 'a' and 'b' are the parallel sides and 'h' is the height. The square's area is simply a², where 'a' is the side length.
For the rhombus, three formulas are provided: P = a · h sidetimesheight, P = d1⋅d2/2 halftheproductofdiagonals, and P = 1/2 · d₁ · d₂ · sinα halftheproductofdiagonalsandsineoftheanglebetweenthem.
Vocabulary: Quadrilateral - A four-sided polygon in plane geometry.
Example: For a rectangle with sides 5 cm and 3 cm, the area would be P = 5 cm · 3 cm = 15 cm².
Definition: Area - The amount of space inside the boundaries of a two-dimensional figure.
Highlight: The trapezoid formula is particularly useful for calculating irregular surface areas and can be applied in various real-world scenarios.
Quote: "P = 1/2 · d₁ · d₂ · sinα" - This formula for the rhombus area is especially useful when diagonal lengths and the angle between them are known.
