The distance will be length of the line divided by 2 because the perpendicular bisector cuts through the line at its centre and at right angles
The mid-point is needed when the perpendicular bisector equation of a straight line is required. The distance formula is used when the length of a line is required.
4x + 3y = 24 crosses the axes at (6, 0) and (0, 8). Therefore its length is [(6 - 0)2 + (0 - 8)2]1/2 = [36 + 64]1/2 = 1001/2 = 10 Mid point = (3, 4) Gradient of given line = -4/3 So gradient of perpendicular bisector = 3/4 Therefore equation of perp bisector: (y - 4) = 3/4(x - 3) or 4y - 16 = 3x - 9 3x - 4y = -7
Every point on the bisector of an angle is equidistant from the sides of that angle. It is understood that the distance of a point from a line is the length of the perpendicular dropped from the point to the line.

So that the arc is mid-way in perpendicular to the line segment
Because both lines and rays are infinite in length and thus have no midpoint.

No. A line of any length can be divided in half - and that is what a bisector is.
Drawing perpendicular bisector for a line:Place the sharp end of a pair of compasses at one end of the line, and open it to just over half of the line. Draw an arc which must intersect the line in the position described. Then put the sharp end at the other of the line and, keeping the compassing at the same length, draw another arc which intersects the first one twice and also the line. Then draw a straight line through the two places where the arcs intersect. This line is the perpendicular bisector. Drawing perpendicular bisector of angle:Places the sharp end of the compass at the point of the angle and, after having opened it arbitraily wide, draw an arc which intersects the two lines meeting to form the angle each once in the said position. Then remove the compass and, always keeping it opened at the SAME length, place the sharp end at each of the two places where the previous arc cuts each of the two lines meeting to form the angle. In this position with the described length, draw a small arc at each of the said places, which should cross each other. Draw a straight line from the point of the angle to this crossing. This should be the bisector of the angle.
