Any ellipse is an oval shape. But all ovals are not all ellipses, some are nothing in particular.
Here's one way to think about an elllipse:-- Mark two black dots on a piece of paper, or stick two nails into a piece of wood.-- Mark a dot anywhere else on the paper, just not on the line between thefirst two.-- Measure the distance of the new dot from the first one, and from the second one,then add those two distances.-- If you draw another dot at every place on the paper where the sum of thetwo distances from the first two dots is the same sum, you'll have an ellipse.-- The first two black dots, or the nails, are the foci (focuses) of the ellipse.-- The farther apart the first two black dots are, the more eccentric the ellipse is ...skinny compared to its length.-- When the first two black dots get so close together that they're the same dot,then you have an ellipse whose eccentricity is zero, and there's a special name forthat ellipse. It's called a 'circle'.Easy way to draw it:-- Tie a piece of string in a loop.-- Drop the loop of string around the two nails.-- Put a pencil point into the loop. Pull it out to the side until there's no slack in the loop.-- Run the pencil around, keeping it against the string with no slack in the loop.You're drawing an ellipse.If you pull out one nail, you're drawing a circle.

An ellipsis. It is used to indicate that something has been omitted from a quotation or to create a pause in writing for dramatic or rhetorical effect.
... is called an "ellipse"
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.

The line of bisection of an ellipse is called the tangent.
