Answer
$hyperbola$, $foci$, $vertices$, $transverse$.
Work Step by Step
A $hyperbola$ curve is defined as all the points in a plane where the difference of distances from two fixed points is a constant. These two fixed points are called the $foci$. If we connect the foci, the line will intersect with the curve at two points called the $vertices$, which are joined by the $transverse$ axis.
