Real-World Examples of Kites and Their Geometric Properties

📚 Quick Study Guide

📐
• Definition: A kite is a quadrilateral with two pairs of adjacent sides that are equal in length.
📏
• Diagonals: The diagonals of a kite are perpendicular.
🧮
• Area: The area of a kite can be calculated using the formula: $A = \frac{1}{2} d_1 d_2$, where $d_1$ and $d_2$ are the lengths of the diagonals.
💡
• Angles: One pair of opposite angles are equal.
🪁
• Symmetry: A kite has one line of symmetry along the diagonal that connects the vertices between the unequal sides.
