Question

problem 4: (lesson 20) complete this sentence with the best of the choices given. a(n) ________ is a line that is perpendicular to a line segment and intersects the line segment at its midpoint. a b c d e segment bisector

Explanation:

Step1: Recall definitions

A segment bisector just divides a line segment into two equal parts. It doesn't have to be perpendicular.

Step2: Identify correct term

A perpendicular bisector is a line that is perpendicular to a line segment and intersects it at its mid - point.

Step3: Analyze other options

An angle bisector divides an angle into two equal angles. A mid - point line is not a standard geometric term for this concept.

Answer:

A. segment bisector is incorrect; the correct term is perpendicular bisector. Assuming the options were something like:
A. segment bisector
B. perpendicular bisector
C. angle bisector
D. mid - point line
E. none of the above
The answer is B. perpendicular bisector
