Given triangle RST, with R (-3,2), S (4,5), and T (7,-2), find the coordinates of its orthocenter.
Maybe I'm doing the math wrong, but I keep getting different answers that won't work out. Thanks for all help.
Find the slope m of the line ST.
The slope of the perpendicular line to ST is -1/m.
Find the perpendicular line to ST passing through A.
Repeat the same thing for RS.
To get orthocenter, find the point of intersection of these two perpendicular lines.
