I need help filling in the blank and answering the question.

1. If you move the two foci of an ellipse together so that they become a single point, then the ellipse will become a/an------.

2. What happens when the major and minor axes are exactly the same length?

circle, circle

    1. The elipse will then become a circle. 2. If they are exactly the same length then you have a truly circular orbit/object, the likes of which you will never see in the real world. I hope this helps!
