Question 699331
<font face="Times New Roman" size="+2">


There are no commonly recognized symbols that designate complementary and supplementary angles.  However, if you are writing a paper that frequently refers to a pair of angles as either complementary or supplementary, you might consider defining your own symbol.  If you are stuck with plain text rendering, such a thing might be rather challenging, but there are a myriad of choices if you are going to do *[tex \LaTeX] typesetting or if you are going to use MathType or MSWord Equation Editor.


Let's say that you are doing plain text.  You could put a statement near the front of your paper or perhaps in a footnote that the symbol @ in the context of this paper means "is complementary to."  Then you could say at any point < A @ < B and have it mean that "Angle A is complemenatry to angle B".
