This document contains an agenda and lesson plan for a geometry class. The agenda includes reviewing a homework problem, learning about the multiplication and division properties of segments and angles, working on example problems, and assigning homework. The lesson plan focuses on teaching students to recognize and use the multiplication and division properties in two-column proofs and computations involving segment lengths and angle measures. Examples of applying these properties are provided.
