Answer 1

Perpendicular bisector.

• Perpendicular means a line or a line segment that makes an angle of $90°$with another line or line segment
• A perpendicular bisector is a line or a line segment divides a given line segment into parts of equal length and intersect at $90°$.

The perpendicular bisector is shown in the image below:

Thus, a perpendicular bisector intersects another line segment at $90°$ and divided it into two equal parts.
