**Task
description**

Before engaging in this task it seems
sensible to prepare ourselves by making a summary of important properties
that we already know about triangles and significant points associated with
triangles.

**Glossary of important terms and triangle properties that are germain
to the task**.

The following terms are important and should be reviewed by the reader before
proceeding with the discussion below. In most cases a short desription of
the term or concept is given and in nearly ALL cases a proof is provided.

Centroid

Circumcenter

Incenter

Orthocenter

Euler Line

Nine point circle

Fermat point

Orthic Triangle

Napoleon's Triangle

Pedal Triangle

Miquel points
