The document discusses the Side-Side-Side (SSS) congruence postulate for proving that two triangles are congruent. It states that if three pairs of corresponding sides from one triangle are congruent to three pairs of corresponding sides from another triangle, then the two triangles are congruent. An example is shown with triangle ABC shown as congruent to triangle DEF based on the three pairs of congruent sides. The homework assignment and problems are also listed.
