Could I name a number in tikz?
I have been drawing some pictures using tikz, and am wondering if I can name a number.
For example, I pick a point $A$ with position angle $alpha=45degree$ on a circle, and a line going through that point with direction angle $beta=alpha+90degree=135degree$ (with is perpendicular to the position vector).
Later I change the point $A$ to be $alpha=60degree$, and then $beta=150 degree$.
Now I change both angles manually. If I can name the first angle $alpha$ and the second angle $beta$, then I only need to change $alpha$: $beta$ will vary accordingly.
Is there a way to do this, naming a number? Thanks!

I didn't understand correctly. Can you add an example of what you want to achieve in the end but can't?

You can use insert path in order to insert paths that are largely the same. This is illustrated in the MWE most of which is illustration.
documentclass[tikz,border=3.14mm]{standalone}
begin{document}
begin{tikzpicture}[insert points/.style={insert path={%
(#1:1) coordinate(A) (#1+90:1) coordinate(B)}}]
% with 45 degrees
path[insert points=45];
% only illustration
draw circle (1);
foreach X in {A,B}
{node[fill,inner sep=1pt,label=right:X] at (X){};}
% second example (shifted to avoid interference)
begin{scope}[xshift=4cm]
% with 60 degrees
path[insert points=60];
% only illustration
draw circle (1);
foreach X in {A,B}
{node[fill,inner sep=1pt,label=right:X] at (X){};}
end{scope}
end{tikzpicture}
end{document}
