An ellipse has 2 foci (plural of focus ). In other words, we always travel the same distance when going from The distance between each focus and the center is called the focal length of the ellipse.

Firstly, in an ellipse, the sum of the distances from a point to the foci is always the same.

There's no distance between them. Clearly, the distance between a and b has to be smaller than 1.5 (by triangle inequality and this mean that b has to be in the circlea,1.5). This section focuses on the four variations of the standard form of the equation for the ellipse. Each ellipse has two foci (plural of focus) as shown in the picture here:
