First attempt at making a riddle, it should be easy for you guys.
One of my siblings idolizes me, constantly trying its best to look like me, which I gladly appreciate.
He even settles down the quarrels between me and the two others siblings, I'm sure they're just jealous of my current position.
Combining our efforts, my beloved sibling and I can easily draw a circle and a square. The two others can too, but in my opinion, our square looks better.
I absolutely need my partner for making the circle and the square, same thing for the two others, else it's not possible if we're alone while doing these.
Our full family is renown internationally, and we have many cousins.
Question : Can you identify me, my family, and the group of four siblings ?
Hint 1 :
When we make a circle, we effectively rotate around a base once.
Hint 2 :
When all 4 of us regroup for calling out someone, we find out that 1 called person out of 3 turns out to be one of our cousins.
Also, regrouped, we can't draw any circle nor any square.
It turns out that we can draw, with some twisting, 1 circle, 2 circles, or a square, when we are regrouped.
Hint 3 :
I'm on almost everyone's hands.
Hint 4 :
You can count on me at any time... Except for science, it bores me.
Hint 5 :
Here I am now.
