what is a hyperbola vertex ?

HELP ! I have no access to a math book over the Holidays and am
trying to help my son before his math test Tuesday. I am an
ex-electrical engineer and have the math background but its rusty.
What are the vertices of a hyperbola ? Are they the points on each
hyperbola closest to each other, e.g. at the 'peaks' of the hyperbolas
?
And is there a formula for determining them ? When the two closest
points are on the x axis or y axis I remember how to find them by
setting y or x equal to zero and solving for the intercepts. But what
if the hyperbolas are not vertically or horizontally aligned along the
axis but rather offset ?
Thanks and happy Holidays ! BTW is there a website that has a
tutorial on parabolas ?

Bob
