I want to draw a triangle (with the package TikZ). I don't know how to draw the line, which links the
BC points. I know I have to use these commands:
(a:b|-c,d). Unfortunately I cannot use any of these commands, so please explain, how to use these commands and what do they mean.
Please, introduce the commands in detail. And also, I need the line, which links the points
AB. I do not need the points and the "
=45°" in my LaTeX document.
