first we should select a position of the theodolite and initial adjustments are to be carried out then take back sight from the BM and then focus on the top of the object which we determine the elevation and take the vertical angle in bothvernier scales. after that take back sight to line of orientation to a known distance and locate a second point. then shift the instrument to the second point do all adjustments and take back sight to the BM and then focus on the top of the object take the vertical angle in bothvernier scales. after that using trigonometrical formula we calculate the elevation of the object.

How many points are needed to determine a unique plane?
A plane can be determined by three points, as long as the three points do not lie along a single line.
How is the angle of elevation affected as the plane flies closer to the person?
The angle of elevation is increased as the plane flies closer because of the decreasing distance.
Three points that determine a plane?
Any 3 points determine a plane.
What determines a plane?
