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°.

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
• Rectangles: P = a • b
• Parallelograms: P = a • h
• Rhombuses: P = (e • f) / 2 (using diagonals) and P = a • h
• Kites: P = (e • f) / 2
• Trapezoids: P = (a + b) • h / 2

Definition: Each shape is clearly defined and its corresponding area formula is provided.

Highlight: The page emphasizes the versatility of these formulas in solving various pole czworokąta (quadrilateral area) problems.

This summary page is crucial for students to quickly recall the necessary formulas when solving problems related to jak obliczyć pole czworokąta o różnych bokach (how to calculate the area of quadrilaterals with different sides).
