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.
A plane can be determined by three points, as long as the three points do not lie along a single line.
The angle of elevation is increased as the plane flies closer because of the decreasing distance.
Any 3 points determine a plane.
three points can determine a plane

single plane method:- let A and B be the two chosen instument station Q be the elevate object whose elevation is required A Band Q lies in the same vertical plane double plane method:- let A and B be the not in the same verticale plane as that of elevayed object Q they are in two vertical planes

the angle of elevation would be the angle between the horizon and the line of sight to whatever object you are measuring to. Lets say for instance that you see a plane, and you determine that it has an angle of elevation of 30 deg. This means that from the horizon, you would need to look up at an angle of 30 degrees to see that plane. below I linked to a diagram which illustrates it quite well. Hope this helped!
If points A, B, and C are not on the same line, they determine a single plane.

The earth is tilted 23 degrees in the orbit plane. This results of lower elevation in the winter and greater elevation in the summer.
The polygon method is most suitable graphical technique for analyzing concurrent forces because it allows for the graphical addition of multiple vectors without the need any complex calculations. This method is particularly useful when dealing with systems of forces acting at a single point or in a plane. By using the polygon method, can visually determine the resultant of multiple forces, which simplifies the analysis and helps in understanding the overall effect of the forces on a system
a single winged plane is called a monoplane
