tikz-rightangles

This is a TikZ library named rightangles that provides a way to draw right angles.

The library is a simple modification of the original library angles.

Note

The code of this library was merged on 2018-06-21 with the standard tikzlibraryangles.code.tex. So after the next official realease of TikZ this library will become useless.

How to use it

• Put tikzlibraryrightangles.code.tex file in a folder accessible by latex. For example in the same folder as your main file.
• Load the library with

\usetikzlibrary{rightangles}

Basic usage examples

You can use right angle pics in the same way you use angle pics.

For example the code

\documentclass[tikz,border=7pt]{standalone}
\usetikzlibrary{rightangles}
\begin{document}
  \tikz \draw (2,0) coordinate (A) -- (1,1) coordinate (B)
    -- ([turn]90:1) coordinate (C)
    pic [draw=red,fill=lightgray,angle eccentricity=.5,pic text=$\cdot$] {right angle = C--B--A};
\end{document}

And you can use it also to obtain right angles in perspective

\documentclass[tikz,border=7pt]{standalone}
\usetikzlibrary{rightangles}
\begin{document}
  \tikz \draw (2,0) coordinate (A) -- (1,1) coordinate (B)
    -- ([turn]49:1) coordinate (C)
    pic [draw=red,fill=lightgray] {right angle = A--B--C};
\end{document}
