This document discusses analytic geometry and ellipses. It begins with objectives of defining key terms of conic sections like ellipses, and solving equations and real-world problems involving ellipses. An activity is described where students can draw an ellipse using a rubber band stretched between two pins. Examples of completed ellipses are shown along with their equations and key properties labeled like foci, vertices, axes, and eccentricity. Students are given practice problems to find properties of ellipses based on given information.
