i salute the whole community!

in signals and systems, I'm learning things about the phasor drawing of the given sinusoidal signs.

when researching on the Internet, the negative phases are counterclockwise
i came across articles that the positive phases are clockwise. but when you do it with the tool, it turns out the opposite

so;
the clock direction that is negative
the positive one came out counterclockwise.

which is the correct information in the picture or the opposite of the information in this picture?

any information that will be given will be honored with honor. thanks

I've never heard the term "clock" direction used with phasors. What is the physical interpretation of positive or negative in this application. Since everything repeats every revolution, I can represent any phasor in multiple ways as positive phase or a negative phase plus or minus any multiple of 2π.

Custom and tradition usually choose the "zero degree" point as the far left part of a circle. The selection of a rotation direction is made, by tradition, to be clockwise, back when clocks rotated, as a handy way to reduce confusion.
Usually, communications work better when all involved apply the same meanings to the words involved.
