Proof of perpendicular lines
WebUsing reductio ad absurdam we can prove: Only one line can be drawn perpendicular to a given straight line from a given point on it. For if we suppose that CF and CG are both perpendicular to AB, then angle ACF is equal to angle ACG ( Postulate 4 ), the smaller to the larger; which is absurd. Dropping a perpendicular WebHere we take the equation of one of the perpendicular lines as the general form of the equation of a line. The general form of equation of a line is as follows. ax + by + c = 0 Let …
