Foci (correct plural of focus)
An ellipse have two focal points.
foci and axes.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.
An ellipse has two focal points. These points are located along the major axis, equidistant from the center of the ellipse. The sum of the distances from any point on the ellipse to these two foci is constant, which is a defining property of an ellipse.
No
An ellipse have two focal points.
foci and axes.
Ellipse is a term for an oval. Specifically it is a shape where the sum of the distance of every point on the ellipse to two points, called the foci, is equal.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.
What are two points inside a ellipse
Yes; the circle is a special case of an ellipse.
An ellipse, a hyperbola.
An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
It is false
The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
