This document provides an overview of indifference curves and their properties. It discusses that indifference curves show different combinations of goods that provide the same level of satisfaction to a consumer. The document outlines several key assumptions of indifference curves, including that consumers have stable preferences and act rationally given prices and income. It then describes properties such as indifference curves being downward sloping and convex. Finally, it briefly discusses indifference maps, budget lines, and how budget lines are tangent to indifference curves at the point of consumer equilibrium.
