An ellipse is the cross section of a cone taken in a plane that is not parallel or perpendicular to the base, or at the same slant as the cone's slant.

The set of all points whose sum of distances to two points is constant.

A ellipse has symmetry along the major axis and minor axis. Usually this is verticle and horiztonal, depending on the orrientation fo the ellipse

1st Equation is wide, 2nd Equation is tall. B is the distance from center to a covertex and A is the distance from a center to a vertex.

Eccentricity of an ellipse is less than 1 because value C (distance from a focus to the center) is always less than the distance A in an ellipse.

To graph an ellipse from an equation in standard form, center the circle at the x-coordinate: the opposite of the number being added to x in parenthasees and y-coordinate: the opposite of the number being added to y in parenthasees. Then graph the vertices and covertecies. Connect the dots in an approximated arc.

A pool ball originating at one vertex of an ellipse is shot through the center of the ellipse. Its path will:

A. pass through both foci then continue toward the other vertex
B. reflect off the inside of the ellipse before reaching either focus
C. not reach either focus
