To adjust a sprinkler to cover only 180 degrees, locate the adjustment collar or the directional lever on the sprinkler head. Most models have a tab or screw that allows you to limit the arc of the spray; turn or slide this to set the desired angle. Some sprinklers may also have a marked guide indicating the range. Once adjusted, test the sprinkler to ensure it operates within the new range.
To make a complete turn around, it takes 360 degrees. This full rotation brings you back to your original starting position. If you only want to turn halfway around, that would be 180 degrees.
There are only 360 degrees in a circle.
because a full circle only has 360 degrees
The only way to circumscribe a circle around a parallelogram is when the parallelogram is a rectangle. This is because only rectangles have all four angles equal to 90 degrees, which allows a circle to be inscribed such that all vertices are equidistant from the center. In general, a circle can be circumscribed around a polygon only if the polygon is cyclic, and rectangles are the only type of parallelogram that meet this criterion.
there are still only 360 degrees in a hexagon
If the in-ground sprinkler system has not been blown out and it is 30 degrees out, it is important to act quickly to prevent the pipes from freezing and potentially bursting. Contact a professional to blow out the sprinkler system as soon as possible to remove any remaining water and protect the system from winter damage.
Newton's third law of motion. The turning of the sprinkler head is the equal and opposite reaction to the water leaving the sprinkler nozzles. The water goes out and the sprinkler nozzle is pushed backward, turning it in a circle because the arm is attached to the middle of the sprinkler. The higher the water flow, the faster the sprinkler spins.
Fire sprinkler systems are effectively already zoned - you don't need to do anything special. When your fire sprinkler system detects a fire, it doesn't set off all the sprinkler heads at once. Instead, each fire sprinkler head goes off when the temperature underneath it reaches a specific temperature, meaning only the ones affected by the fire will go off.
Jupiter does not really have seasons, since it's axial tilt is only around 3 degrees. It's temperature at the 1 bar level is around 165 degrees Kelvin, around -108 degrees celcius.

winterize it only if you want it to work in the future
A sprinkler pressure vacuum breaker is used to prevent backflow of contaminated water into the clean water supply. It helps maintain proper pressure in a sprinkler system by ensuring that water flows in one direction only, preventing any potential contamination from entering the system.
If there are only three electron groups around an atom, they would be arranged in a trigonal planar geometry. This arrangement minimizes repulsion between the electron groups, placing them 120 degrees apart in a flat plane. The central atom would have a bond angle of approximately 120 degrees between the electron groups. If one of the groups is a lone pair, the geometry would adjust to a trigonal pyramidal shape.

There are several ways to come at this answer, most of them way too technical and arcane to bother with. The easiest answer to state and understand may be simply the fact that each parallel of latitude goes all the way around the Earth, but each meridian of longitude only goes half-way around the Earth, so you need more of them to cover the whole Earth. Does that do anything for you ? And by the way . . . there are only 180 degrees of latitude.
Yes, each tooth is only 2-4 degrees which you can simply adjust timing to compensate .
