This document provides a lesson on ellipses. It contains: 1) An assessment with multiple choice questions about the key properties of ellipses, including that the foci are two points inside the ellipse, and that the sum of distances from any point on the ellipse to the two foci is a constant. 2) A request to write the equation of an ellipse in general and standard form. 3) An answer key for the multiple choice assessment and space to write the standard form equation.
