Question

which of the following can be measured? line angle point ray

Explanation:

A line extends infinitely in both directions, so its length can't be measured. A point has no dimension, so it can't be measured. A ray extends infinitely in one direction, so its length can't be measured. An angle is formed by two rays (or lines) meeting at a vertex, and its measure (in degrees or radians) can be determined using tools like a protractor.

Answer:

B. angle
