Hi ,(adsbygoogle = window.adsbygoogle || []).push({});

I have drawn a line between two co-ordinates say (x1,y1) and (x2,y2). I have a point called (x3,y3) . From the point (x3,y3) i need to draw a perpendicular line to (x1,y1) and (x2,y2). so that i will be able to find the perpendicular distance . Is there any formula for calculating or drawing this perpendicular line. Any equations for finding this? I have depicted the question in terms of diagram which is attached along with this message.

pls help.

Thanks in advance
