Consider a hyperbola $K$ whose foci are $F_1$ and $F_2$.

The conjugate axis of $K$ is the line segment joining the vertices of $K$.

Also known as
Many sources give this as the minor axis, but at the policy is to use the latter term to mean the (infinite) straight line which is the perpendicular bisector of the transverse axis of $K$.
