This document defines and describes the key properties of a parabola. A parabola is a collection of points equidistant from a fixed focus point and directrix line. The vertex is the starting point, focus is the fixed interior point, directrix is the exterior line, and axis of symmetry bisects and connects the vertex and focus. Properties like opening direction and the vertex, focus, directrix, axis of symmetry, and latus rectum positions depend on the equation form. Examples of parabola equations are given to find these key elements.
