Tikz: Tikz 스타일의 각도 표시를 위한 다양한 방법

Question

이 아름다운 대답을 계속해서,다음과 같은 추가 각도 표시가 가능합니까? ((1) 중앙에 점이 있는 각도, (2) 가능하면 사용자 정의할 수 있는 장식이 있는 보라색 각도(세그먼트 번호, 길이, 거리, 색상 등), (3) 각도 여러 호.

Answer 1

여기에 제안이 있습니다. Kpym이 댓글에서 친절하게 설명했듯이 각도 구성에는 호와 채우기라는 두 가지 경로가 있습니다. Ti를 예방해야 한다케이Z는 장식을 두 번 그렸습니다. 이 답변은 style 과 함께 제공되는데 insert angle lines, 이는 두 개의 인수, 즉 선 수와 연결해야 하는 꼭지점을 취합니다. 예는 다음과 같습니다

\pic [draw=red,angle radius=1cm,insert angle lines={3}{A}] 
    {angle = C--A--B};

점에 대한 두 번째 스타일이 있습니다

\pic [draw=blue,angle radius=1cm,insert angle dot={B}] {angle = A--B--C};

이러한 마크의 스타일을 변경하려면 을 조정하십시오 every angle mark. 다음은 MWE입니다.
