Which axis of a hyperbola has the two vertices as its endpoints?
AThe transverse axis
BThe conjugate axis
CThe horizontal axis
DThe asymptote axis
Answer & Solution
Correct answer: A. The transverse axis
1. A hyperbola has two axes of symmetry crossing at its center.
2. The one carrying the vertices at its ends is the transverse axis.
3. The conjugate axis is perpendicular to it and carries the co-vertices instead.
4. Calling it the horizontal axis fails because the transverse axis can be vertical.
