Advanced Quadrilateral Calculations

This page continues with more complex wzory na pole czworokąta (formulas for quadrilateral areas). It focuses on shapes with specific given dimensions and angles, demonstrating how to use trigonometric functions in area calculations.

The page includes a detailed solution for finding the area of a trapezoid-like shape. It uses the formula P = (a + b) • h / 2, where 'a' and 'b' are parallel sides and 'h' is the height.

Example: A trapezoid with parallel sides of 6 and 10 units, and a height of 3 units, has its area calculated as P = (6 + 10) • 3 / 2 = 24 square units.

Highlight: The page emphasizes the importance of identifying key dimensions and angles in irregular shapes to apply the correct formulas.

Definition: Pole czworokąta wypukłego (area of a convex quadrilateral) is introduced, showing how to approach shapes with all interior angles less than 180°.

Rhombus and Parallelogram Area Calculations

This page focuses on specialized formulas for rhombuses and parallelograms, introducing more advanced wzory na pole czworokąta (formulas for quadrilateral areas).

For rhombuses, it introduces the formula P = a² • sinα, where 'a' is the side length and α is one of the angles. This formula is particularly useful when dealing with rhombuses where only the side length and one angle are known.

Example: For a rhombus with side length 12 and an acute angle of 30°, the area is calculated using P = 12² • sin30° = 144 • 1/2 = 72 square units.

The page also covers parallelograms, using the standard formula P = a • h, where 'a' is the base and 'h' is the height perpendicular to the base.

Vocabulary: Pole rombu (area of a rhombus) and pole równoległoboku (area of a parallelogram) are explicitly defined and their formulas explained.

Highlight: The page emphasizes the relationship between trigonometric functions and area calculations in rhombuses.

Summary of Quadrilateral Area Formulas

This final page provides a comprehensive summary of wzory na pola czworokątów (formulas for quadrilateral areas) for various shapes. It serves as a quick reference guide for students.

The page includes formulas for:

• Squares: P = a²
