When the vertical circle of the theodolite is to the left of observer, it is in face left position. Similarly when the vertical circle is to the right of observer it is in face right position.
Face left observation(In theodolite survey):If the face of the vertical circle is to the left of the observer, the observation of the angle is known as Face left observationFace Right observation(In theodolite survey):If the face of the vertical circle is to te right of the observer, the observation of the angle is known as Face right observation
measurments are a tipe of tape that measures=
taking readings using theodolite keeping the vertical circle of the instrument on left side of the observer is called a face left observation and to measure horizontal angle the instrument is rotated(swing) in horizontal plane with respect to the vertical axis in a clockwise direction called rigt swing.
Because it is easier to read left from right instead of right to left
A positive number is to the right of the zero on the number line. (I believe that is what you meant to ask).
Face left and face right are taken to reset the posoition of the theodolite so additional measurements can be raken

*find a theodolite or total station *check for collimation *check theodolite vertical axis *set up the theodolite a distance away from the foot of the tower, or closer but using a diagonal eye piece *use left face to bisect bottom point and clamp the horizontal plate *check the tower zenith transit and use the right face to bisect the bottom point and do as explained above *dont forget to record readings of every stage.
left to right
it faces left but looking at it should always face right
It does not matter whether it's right or left as long as they face the entrance of the room or house.
The head is to the right.
At Auschwitz 'to the left' meant immediate gassing; 'to the right' meant 'selected for work'.
