So I'm pretty new to Latex. Few days ago I discovered a package called tkz-euclide and it looked pretty interesting. Later on I found this pdf coursebook (http://linorg.usp.br/CTAN/macros/latex/contrib/tkz/tkz-euclide/doc/TKZdoc-euclide.pdf) and if i want to use some commands from it in overleaf (the online compiler) it says the sequence was never def'ed. In preamble I put all my casual packages (idk if some may be unnecessary). So here is little example of what causes the crash:
\documentclass[12pt]{article}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{subfig}
\usepackage{yfonts}
\usepackage{wrapfig}
\usepackage{pstricks-add}
\usepackage{tikz} % remove this
\usepackage{float}
\usepackage{amssymb}
\usepackage{marvosym}
\usepackage{pgfplots}
\usepackage{amsmath}
\usepackage{fancyhdr}
\usepackage{xcolor}
\usepackage{tkz-euclide}
\usepackage{etex}% remove this
\usepackage{siunitx}
\usepackage{mdframed}
\usepackage[margin=1in]{geometry}
\usepackage{systeme,mathtools}
\usetikzlibrary{calc, babel, intersections, plotmarks, matrix, quotes, angles, mindmap, arrows, folding, shapes, trees, hobby, backgrounds, positioning, shapes.geometric}
\usetkzobj{all} % remove this if tkz-euclide version >3
\pagestyle{fancy}
\fancyhf{}
\rhead{----- \\ 06.04.2020}
\lhead{Zadanie}
\rfoot{Strona \thepage}
\begin{document}
\section*{----}
\begin{figure}[h]

\begin{tikzpicture}
\tkzDefPoints{0/0/A,5/1/B,1/4/C}
\tkzClipPolygon(A,B,C)
\tkzDefTriangleCenter[ortho](B,C,A)
\tkzGetPoint{H} \tkzLabelPoints[below](H) %<-----THIS LINE
\end{tikzpicture}
\end{figure}
\end{document}
And i noticed it's the \tkzDefTriangleCenter[ortho](B,C,A)
command.
Here is a screenshot:
Anybody knows the sulution? Thanks for reading!
