Geometry of a Triangle: Introduction

In the last section we talked about quadrilaterals and how algebra is used to solve problems involving quadrilaterals. In this section we will discuss congruent and similar triangles. Suppose you want to draw a similar version of a triangular team logo on a poster for school. Similar triangles can be used to construct the logo. You may need to use algebra to complete the drawing. In this section we will discuss how this is done.
