Introduction

This chapter introduces different segments within triangles and how they relate to each other. We will explore the
properties of midsegments, perpendicular bisectors, angle bisectors, medians, and altitudes. Next, we will look at
the relationship of the sides of a triangle, how they relate to each other and how the sides of one triangle can compare
to another.
