Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Hyperbola?Ancient Greece, with systematic study by Apollonius of Perga around 200 BC
2. What is the eccentricity range?e > 1, distinguishing it from other conic sections
3. What is the key physical principle?The reflective property, enabling applications in optics and wave redirection
4. Why does a hyperbola have an eccentricity greater than 1?The eccentricity measures how stretched a shape is. For a hyperbola it is always bigger than 1, which makes it open and separate, unlike circles, ellipses, or parabolas.
5. How do the foci of a hyperbola work?A hyperbola is the set of points where the difference between the distances to two fixed points (the foci) is always the same. That constant difference is called 2a.

Conic Sections: A family of curves (circle, ellipse, parabola, hyperbola) formed by the intersection of a plane and a double cone.
Foci: Two fixed points that define a hyperbola; their geometric relationship dictates the curve's shape and properties.
Asymptotes: Lines that the branches of a hyperbola approach infinitely closely but never intersect.
Eccentricity: A measure of how much a conic section deviates from being circular; for a hyperbola, it is always greater than 1.
