How do you construct the perpendicular to the line that passes through point x?
draw an arc (circle) centred on point X, but intersects A to B at or before A widen the compass so to say approximately twice the radius (length) between those marks on A to B then draw an arc from each of those points making certain the intersect (cross over) above and below the line A to B. using a rule draw a line through those intersection marks through A to B, through X A–I1————-X———-I2——-… i1 & i2 are equidistant from X…it could just as easily be A————-X————-C———… draw an arc or circle of length X to A to identify C draw an arc or circle centred on A of length A..
