Dynamic Rectangles, also called Root Rectangles, are the series of rectangles which grow from the diagonal of a square. They're harmoniously linked to each other and can have a powerful effect on viewers. That's why they're specifically chosen as the shape for many designs. You'll be surprised at the many places these particular rectangles appear around us from diplomas, writing paper and household objects to worldwide sacred art, crafts and architecture from the many cultures who discovered their remarkable properties. This highly illustrated book is its own geometry course and will teach you about the fascinating geometry of these rectangles through hands-on activities with a compass and straightedge. After learning the simple geometry, you're invited to do constructions on images of art and objects which use these proportions and discover for yourself how they were intelligently designed. If you're an artist, architect or designer, this information can be quite valuable. Learn from the masters how they used these remarkable rectangles to create the most beautiful and compelling works. You're probably familiar with many of them without knowing the secrets of their proportions.
