The point is not the code, but your logic approach, you have solved my problem,  I have a doubt (setq f 1e-1) I can't understand this. thanks again for your help bro wish you a happy life

That is the fuzz value EQUAL uses to compare the angles and lengths. It's the same as 1e-1 = 0.1 .. 1e-2 = 0.01 and so on.

 

And thanks!

Just a personal preference. I like the way COND formats in the vlide.

And yes if PROGN is needed I generally opt for COND.
