¿Curva de un círculo?

Question

AB son dos puntos de una circunferencia. Al insertar texto en Geogebra, uso LaTex y no tengo la opción de asignar un signo de curva encima de AB

Answer 1

así usando matemáticas:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[frenchb]{babel}
\usepackage{mathabx}

\begin{document}
$\wideparen{abc}$
$\wideparen{AB}$
\end{document}

Y otra forma de usar tikz:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[frenchb]{babel}
\usepackage{tikz}

\begin{document}
\tikz[overlay, remember picture] \node[name=orig, inner sep=0mm] {abc};
\tikz[overlay, remember picture] \draw (orig.north west)
to[out=45,in=135] (orig.north east);
\qquad
\tikz[overlay, remember picture] \node[name=orig, inner sep=0mm] {AB};
\tikz[overlay, remember picture] \draw (orig.north west)
to[out=45,in=135] (orig.north east);
\end{document}
