Question

1. a line that crosses segment at right angles while dividing the segment in half is called

a perpendicular bisector
an intersector
a bidivider
a traversal

Explanation:

To solve this, we analyze each option:

• A perpendicular bisector is defined as a line that intersects a segment at 90° (right angles) and divides it into two equal parts (bisects it).
• An intersector is not a standard term for this concept.
• A bidivider is not a recognized geometric term for this.
• A transversal is a line that intersects two or more lines, not specifically related to bisecting a segment at right angles.

So the correct term matching the description is a perpendicular bisector.

Answer:

A. a perpendicular bisector
