Question

Name a secant of the sphere and a chord of the sphere.

Short answer

Chord is $AB$ and secant is $AB$.

Step-by-step solution

Step 1. Given information. 

Figure is given.

Step 2. Concept used.

Chord of the sphere is the segment that joins any two points of the circle.

Secant is a plane containing a nontrivial section of a sphere.

Step 3. Name the secant and chord.

Chord of the sphere is the segment that joins any two points of the circle.

Therefore, chord is $AB$.

Secant is a plane containing a nontrivial section of a sphere.

Therefore, secant is $AB$.
