# Different positions of an object when it rotates

Suppose a stick rotates as shown in the picture, what are called the positions shown with numbers. Or how do you describe these positions by some words? Specially the number 1,

can I say "the number one is horizontally aligned"

or maybe just "the number one is in horizontal position"?

Moreover, it's not much a formal mathematics question.

• Are you asking for a term that distinguishes 2 and 4 from all of the others? Maybe "angled" or "diagonal" or "at 45 degrees". Sep 6, 2016 at 14:53
• You might also need to consider positions 6 and 8, which in terms of slope are the same as 2 and 4 respectively.

• Informally: horizontal, vertical and diagonal might convey the idea. For a more precise explanation I would probably resort to mathematics: specify a centre of rotation and angles of rotation of 45, 90, 135 and 180 degrees.

• @ahmad I'll let you decide but since this looks similar to a circle, those increments look like arcs of a circle. regentsprep.org/regents/math/geometry/gp15/circlearcs.htm AND mathwords.com/a/arc_circle.htm Sep 6, 2016 at 15:17
• @stangdon No, I meant the first one, I modified my question. Sep 6, 2016 at 15:19

Number 1 can be called flat, horizontal, or 'laying down'. You can also refer to it as the one on top.

Number 3 would similarly be called upright, vertical, or 'standing up'.

If you don't need to know with precision exactly where these intermediate positions are, you could refer to them as just that - 'intermediate positions'. Not sure if this is what you are looking for.

• Thank you, however I meant more the number one position Sep 6, 2016 at 15:30

The positions could be described by the points of the compass. Going clockwise : North, North-East, East, South-East, South, etc.

If there were 12 sticks you could use the clock positions : 1 o'clock, 2 o'clock, etc.

• "Number one is in the north position."
• "Number two is is in the northeast position.

or

• "Number one is on top."
• "Number two is in the upper right".
