If, and only if, a = b, it is a hyperboloid of revolution. A hyperboloid of one sheet can be obtained by revolving a hyperbola around its transversal axis. Alternatively, a hyperboloid of two sheets of axis AB is obtained as the set of points P such that AP−BP is a constant, AP being the distance between A and P. Points A and B are then called the foci of the hyperboloid. A hyperboloid of two sheets can be obtained by revolving a hyperbola around its focal axis. In mathematics, a set can be thought of as any collection of distinct things considered as a whole. ...

A hyperboloid of one sheet is a doubly ruled surface; if it is a hyperboloid of revolution, it can also be obtained by revolving a line about a skew line. In geometry, a surface is ruled if through every point of there is a straight line that lies on . ...
In geometry, two lines are said to be skew lines if they do not intersect but are not parallel. ...
An elliptic hyperboloid of one sheet. The wires are straight lines. For any point on the surface, there are two straight lines lying entirely on the surface which pass through the point. This illustrates the doubly ruled nature of this surface. A degenerate hyperboloid is of the form Image File history File links Ruled_hyperboloid. ...
