Quadrilateral Area Calculations
This page introduces methods for calculating the pole czworokąta (area of a quadrilateral) with different side lengths. It demonstrates the process through two detailed examples.
The first example shows how to calculate the area and perimeter of an equilateral triangle. The solution uses the formula P = a • h, where 'a' is the side length and 'h' is the height. The height is calculated using trigonometry, specifically the 30-60-90 triangle properties.
Example: For an equilateral triangle with side length 8, the area is calculated as P = 8 • 4√3 = 32√3, and the perimeter is 24.
The second example deals with a more complex quadrilateral, likely a kite or rhombus. It uses a similar approach but with more intricate calculations involving multiple angles and side lengths.
Highlight: The page emphasizes the importance of breaking down complex shapes into simpler components for easier calculation.
Vocabulary: Pole czworokąta nieforemnego (area of an irregular quadrilateral) is introduced, showcasing how to approach non-standard shapes.
