Web10.0. 2. =. 12.5. An ellipse has two focus points. The word foci (pronounced ' foe -sigh') is the plural of 'focus'. One focus, two foci. The foci always lie on the major (longest) axis, spaced equally each side of the center. If the major axis and minor axis are the same length, the figure is a circle and both foci are at the center. WebOther theorems in respect to the ellipse might be added; but enough have been given to illustrate the theory. The above list contains the most of the important propositions. If the conic be a hyperbola, two of the foci are still real, and two imaginary; but the imaginary foci coincide in position with the real foci of the conjugate hy-perbola.
