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.
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 line segment that divides a circle in two is a chord.If the two parts of the circle are equal, the line segment is a diameter.See 'The Parts of the Circle' in Sources and related links, below.
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
