Question

which is the definition of a line segment?
a figure formed by two rays that share a common endpoint
the set of all points in a plane that are a given distance away from a given point
a part of a line that has one endpoint and extends indefinitely in one direction
a part of a line that has two endpoints

Explanation:

• The first option defines an angle (two rays with a common endpoint).
• The second option defines a circle (set of points at a given distance from a center).
• The third option defines a ray (part of a line with one endpoint, extending infinitely).
• The last option matches the definition of a line segment: a portion of a line bounded by two endpoints.

Answer:

D. a part of a line that has two endpoints (assuming the last option is labeled D; if the original labels were different, adjust the label but keep the text: e.g., if the last option was the 4th one, "the 4th option: a part of a line that has two endpoints")
