This document contains notes from a math lesson on using unique triangles to solve problems. It discusses the five conditions for triangle congruence: three sides, two sides and an included angle, two angles and an included side, two angles and a non-included side, and two sides and a non-included angle of 90 degrees or greater. Examples are given of applying these conditions to show that triangles are congruent and that corresponding parts are equal. The document also lists assignments and tests for the class.
