hi, is there an equation to finding the perpendicular bisector of a line.
for example i had a line b (1,1) and c(8,1) and a was (6,5) how would i find the bisector from a going through line bc?
first off, the slope of a perpendicular line is -1/m (m=slope). since you can find the slope of the line going through points (a) and (b) by "rise/run" take the negative reciprocal of "m" and use the point slope form.
