No, it means it's at right angles to the line. You may be confusing it with bisector
It is a perpendicular line (a vertical line) that divides the triangle into two equal parts.
When a line divides another in two equal parts, it is called a bisector. If the bisector happens to cross the other line at right angles, it is called a perpendicular bisector.
The midpoint divides a line segment into congruent parts.
A perpendicular bisector line depending on what type of triangle it is.
bisector
It is a line which cuts a line segment into two equal parts at 90°.
The midpoint.
The points on the perpendicular bisector of a segment are equidistant from the segment's endpoints. This means that if you take any point on the perpendicular bisector, it will be the same distance from both endpoints of the segment. Additionally, the perpendicular bisector is a line that divides the segment into two equal parts at a right angle.
It is an asymptote.
90 degree bisector
A point on a line segment that divides the segment into two equal parts is a midpoint.
A property used in the construction of a perpendicular bisector is that it divides a line segment into two equal parts while forming right angles (90 degrees) with the segment. This means that any point on the perpendicular bisector is equidistant from the segment's endpoints.
