Okay, if we're looking for orthocenter, which is where the altitudes go together, and we're going to look.
00:06
Oh, look, this one has a nice little vertical line.
00:09
Remember, verticals and horizontals to make our life easier because this one's equation is.
00:20
So, dc has a slope of undefined because it is vertical.
00:28
So then what we want to do is get a line that, goes right here.
00:40
Oh cool.
00:42
So we're going to do this line right here.
00:44
I'm going to come back here, pen.
00:46
Nope, let's know i don't want this one.
00:49
So we want this line.
00:51
I'll put a little bit over so we can see that it's right there...
