This document discusses proportional relationships in similar triangles and how to use them to find perimeters and altitudes. It introduces the Proportional Perimeters Theorem, which states that if two triangles are similar, their perimeters are proportional to their corresponding sides. It also presents Theorem 6.8, which says that if two triangles are similar, their altitudes are proportional. The document provides exercises and homework problems for readers to practice applying these theorems about similar triangles.
