So, take a line (line 1), and from that determine it's rise and it's run (ie. its slope). Now, if you were to rotate the things 90 degrees and then overlap this perpendicular line (line 2) on to the original line 1, you would see that rise2=run1, and run2=rise1. You're essentially dealing with the same numbers, just SK19https://www.blogger.com/profile/17228027233405770851noreply@blogger.comtag:blogger.com,1999:blog-5639270444406781623.post-88903996548143342242007-04-11T09:03:00.000-07:002007-04-11T09:03:00.000-07:00Mathematically, if line 1 has a slope of m1, then ...<I>Mathematically, if line 1 has a slope of m1, then a perpendicular line 2 will have a slope m2=(-1/m1).</I><BR/><BR/>Why?ehttps://www.blogger.com/profile/09267780684300310845noreply@blogger.com
