Famous Examples of the Golden Ratio in Art & Architecture

📚 Quick Study Guide

• 📏 The Golden Ratio, often denoted by the Greek letter phi ($\phi$), is approximately equal to 1.618.
• 🎨 It's found when a line is divided into two parts such that the ratio of the whole to the longer part is the same as the ratio of the longer part to the shorter part.
• 🏛️ In art and architecture, it's used to create aesthetically pleasing and balanced compositions.
• 🔢 The Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, ...) is closely related; as the sequence progresses, the ratio of consecutive numbers approaches the Golden Ratio.
• 📐 A Golden Rectangle has sides in the Golden Ratio; successively smaller Golden Rectangles can be drawn inside it, creating a spiral.
