Answer:
B
Step-by-step explanation:
- In mathematics, we usually label a segment using two letters, one at the beginning of the segment and the second one at the end.
- On the other hand, in mathematics, angles are labeled using 3 letters (∠ABC).
- Lines are labeled using just one capital letter (where the line starts)
- And finally a plane is generally labeled using 3 letters (Plane ABC)
Therefore a geometric figure labeled CD would be a segment and the correct answer is B)
