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
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
No. Two rights make you face the opposite direction you are facing. So you don't go left or right.
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
There is no such thing as a left or right handed bowling ball. When the ball is drilled the pattern will be based on the left hand or right hand measurements.
The head is to the right.
Left eye, right eye, left nostril, right nostril, upper lip.
