Answer:
- 5. Foci, 6. eccentricity, 7. Center, 8. Hyperbola
Explanation:
Below statements include the required information or property
- 5. An ellipse is "the set of all points in a plane such that the sum of the distances from two fixed points (foci) is constant".
- 6. In an ellipse, the ratio c/a is called the eccentricity and is denoted by the letter e . Eccentricity measures the elongation of an ellipse. The closer e is to 0, the more an ellipse looks like a circle.
- 7. A circle is a set of all points in a plane that are all an equal distance from a single point, the center.
- 8. Hyperbolas have a center and two foci, but they do not form closed figures like ellipses
