What else can I help you with?
If you move the two foci of an ellispe together so they become a single point what does the ellispe become?
A circle.
Is Ellispe a polygon?
No it is not. An "Ellispe" is not even a recognised word!. In any case, a polygon is a plane space enclosed by straight lines. An ellipse consists of a curved line, not straight lines.
A squashed circle this has no straight edges?
Oval or ellispe is a shape like a slightly squashed circle.
Which eccentricities represent most elongated ellispe?
The elongation of the ellipse increases as the eccentricity increases from 0 to 1. For eccentricity zero it's a circle, and with eccentricity 1 it's a parabola. They are all a class of curve called a conic section. If you can find a torch (flashlight) that produces a conical beam, shine it directly at the wall and you get a circle. Shine it at an inclined angle and you get an ellipse. If the angle is increased so that one side of the cone is parallel to the wall, you see a parabola on the wall. Any more of an angle and you get the 4th conic section, a hyperbola.
