Final answer:
A perpendicular bisector is a line that divides a line segment into two equal parts and is perpendicular to the line segment.
Step-by-step explanation:
In mathematics, a perpendicular bisector is a line that divides a line segment into two equal parts and is perpendicular to the line segment. To understand perpendicular bisectors, imagine you have a line segment. The perpendicular bisector is a line that intersects the line segment at its midpoint and forms a right angle with it. It divides the line segment into two equal halves.
This concept is commonly used in geometry and can help solve problems involving line segments, triangles, and circles.
