This method is used if there are more than one angles to be measure from a certain station point. Consider the following fiqure, we will measure angles AOB and BOC using this method.
Procedure- Setup the theodolite at station O, bisect the point A with a certain circle reading with face left.
- Rotate the instrument in clockwise direction and bisect B, note the circle reading.
- Then rotate and the telescope till it bisect the point C, note this circle reading also. All these reading will book into face left position.
- Transit the telescope and rotate the instrument through 180°, this time bisect the point C firstly and then rotate telescope in anti clockwise direction towards B and then ultimately towards A. Put these readings in face right position.
- You can do more than one sets of measurements for the accurate results, i have done one set and booking method is as follows,

What is the angle between the ramp and the horizontal?
The angle of inclination.
Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
What is the measure of the supplementary angle of an interior angle?
The measure of the exterior angle.
Find the measure of angle and if the measure of angle abc60 the measure of angle and is represented by 5x 7 and the measure of angle dbc is represented by 9x-3?
No cheating!
When 15 is subtracted from the measure of an angle the result is the measure of a right angle what is the measure of the original angle?
15
How do you measure disc angle of a disc plow?
Disc angle has main two angle : 1. Vertical angle 2. Horizontal angle
What is tacheometric surveying?
the special type of theodolite used to measure horizontal and vertical distance and horizontal angle.
What is a horizontal angle?
A horizontal angle is an angle between lines on a horizontal plane.
What is horizontal as opposed to at an angle?
this is horizontal: ---------------------------- / / this is at an angle: / / /
What does slope determine?
Slope is the angle compared with the horizontal, where the horizontal is 90° to the vertical, which can be measured with a plumb line. So, put a weight on a string, measure the angle of the string to the angle you are measuring, subtract 90° and that will give you the slope.
What angle has the same horizontal displacment as 20 degrees?
20 degrees is a measure of angular displacement. This cannot be converted to lateral (horizontal) displacement.
How do you work out angles with only numbers. for example im trying to make a 30 degree angle with only a straight ruler is it possible for me to work a height and apply the angle?
For certain angles, the answer is yes. For 30o to the horizontal (in the positive x direction), you need to measure the horizontal distance to be twice the vertical distance. For example, draw a triangle with a base length of 10cm and, at a right angle to the base, measure a height of 5cm. The angle to the horizontal (the smaller angle) will be 30o. (The opposite is true for the angle of 60o).
The angle formed by a horizontal line?
The angle formed by a horizontal line is 180o.
What is vertical and horizontal line?
horizontal lines are lines which may be at the angle of 00,1800,3600.if vertical lines stand on horizontal lines it is in the angle of 900
What is the angle between the ramp and the horizontal?
The angle of inclination.
What angle does his velocity make with the horizontal.?
The angle that the velocity makes with the horizontal is called the launch angle. It can be calculated using trigonometry by finding the arctangent of the vertical component of the velocity divided by the horizontal component.
What is angle of Depression?
Angle of depression is the angle between a horizontal line and the line joining the observer's eye to some object beneath the horizontal line. ^_^
