Tikz:Tikz 樣式中角度標記的更多方法

繼續這個美麗的答案,是否可以有以下附加角標記? ((1)以點為中心的角度;(2)帶有裝飾的紫羅蘭色角度,如果可能的話,可以定制它(段數,長度,距離,顏色等);(3)帶有裝飾的角度多個圓弧。

答案1

這是一個建議。正如 Kpym 在評論中友好地解釋的那樣,角度構造有兩種路徑:圓弧和填充。人必須防止鈦kZ從繪製裝飾兩次。這個答案帶有一個 style insert angle lines,它有兩個參數,行數和它們應該連接到的頂點。一個例子是

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

點還有第二種樣式

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

如果您想要變更這些標記的樣式,請調整every angle mark。這是 MWE。
