This document discusses key principles of design including proportion, balance, emphasis, movement, rhythm, pattern, harmony, and unity. It provides examples of how these principles are used in artworks such as depictions of the human body by Leonardo da Vinci, self-portraits by Frida Kahlo demonstrating different types of balance, and paintings showing movement by artists like Edgar Degas and Balla. These design principles and artistic examples help illustrate how elements are arranged both symmetrically and asymmetrically for visual impact.
