tikz, Draw three lines in one path command

I want to create the following:

![Screen Shot 2025-08-02 at 17.53.55.png](/image?hash=9456e7fdde16ead77f44168fb7bfb9317ef2c415ac7370574541a5d1b60cf75b)

My tikz code is
```
\draw (-278,-308)--++(-64,0) -- +(28,27) (-342,-308)-- +(29,-24);
```

I want this path to be interpreted as follows:
Move the pen to (-278,-308) (point `pt1`) and draw a segment 64 units left of it (point `pt2`); draw a segment to the point 28 units above and 27 units to the right of `pt2` (this is `pt3`). Now draw an additional segment from `pt2` 29 units to the right and 24 units below `pt2`.

As you can see my path almost does that and lacks line joins.

I am looking for an approach to keep `pt2` in the memory so to draw the last segment from there using the `+` or `++` operator.

MWE:
```tex
% !TEX TS-program = lualatex
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[scale=0.1]
\draw (-278,-308)--++(-64,0) -- +(28,27) (-342,-308)-- +(29,-24);
\end{tikzpicture}
\end{document}
```

To get nice line joints, I would use a different approach: don't draw a line from p2 to p3 and instead draw arrow tip in one go:


```
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[scale=0.1,line width=3mm]
\draw (-278,-308)
  --++(-64,0) 
    ++(28,27) 
  -- ++(-28,-27) 
  -- ++(28,-27)
;
\end{tikzpicture}
\end{document}
```

(that's basically how I draw 33 and similar numbers in https://ctan.org/pkg/cistercian in order to get a nice spiky peak)
