Continuando con esta hermosa respuesta,¿Es posible tener las siguientes marcas de ángulos adicionales? ((1) El ángulo con el punto en el centro; (2) los ángulos violetas con adornos, si es posible, con la posibilidad de personalizarlo (números de segmento, longitud, distancia, color, etc.); (3) ángulos con múltiples arcos.
Respuesta1
He aquí una propuesta. Como amablemente explicó Kpym en los comentarios, hay dos caminos para la construcción del ángulo: el arco y el relleno. Hay que evitar que TikZ por dibujar la decoración dos veces. Esta respuesta viene con un estilo insert angle lines
, que toma dos argumentos, el número de líneas y el vértice al que deben conectarse. Un ejemplo es
\pic [draw=red,angle radius=1cm,insert angle lines={3}{A}]
{angle = C--A--B};
Hay un segundo estilo para el punto.
\pic [draw=blue,angle radius=1cm,insert angle dot={B}] {angle = A--B--C};
Si desea cambiar el estilo de estas marcas, ajústelo every angle mark
. Aquí está el MWE.
