How do tu know when a circulo, círculo is upside-down?

When ever I draw a circulo, círculo I start at the top. So if I see that the circulo, círculo starts at the bottom, it's upside down. Silly, but it works in a round about way.

I put a mark on parte superior, arriba of it...so when I see the mark down then I know its upside-down...

Silly I know, but it works! xD (no mean comentarios plz!)

When it's not right side up.

When the floor is above tu and the ceiling is below?

oh your so silly! Im a wizard and only wizards know the answer! *sighs* i amor silly geese!

I have never thought about that XD.

I don't think circles have a up o upside-down side.

Nice pregunta :)

Don't have an answer though...

I NORMALLY DON'T KNOW IF A circulo, círculo IS UPSIDE DOWN UNLESS I SEE SOMEONE ELSE DRAW IT STARTING AT THE BOTTOM. BUT IF I JUST SAW A CIRCLE, I'M NOT SUREI COULD TELL.

por turning your head upside down to see for yourself.
