Let $K$ be an ellipse whose foci are at $F_1$ and $F_2$.
Major Axis
The major axis of $K$ is the line segment passing through both $F_1$ and $F_2$ whose endpoints are where it intersects $K$.
Minor Axis
The minor axis of $K$ is the line segment through the center of $K$ perpendicular to the major axis of $K$ such that its endpoints are the points of intersection with $K$.
