| Q.137 | The principle behind the Two theodolite method used for setting a simple circular curve is : | |
| Ans | A. The deflection angle for any chord is equal to the deflection angle for the previous chord plus the tangential angle for that chord. | |
| B. Angle between the tangent at the point of curve and the chord to a point is equal to the angle which that chord subtends in the opposite segment at the point of tangency.. | ||
| C. The deflection angle to any point on the curve is the angle at the point of curve between the back tangent and the chord from point of curve to that point. | ||
| D. Angle between the tangent at the point of curve and the chord to a point is equal to twice the angle which that chord subtends in the opposite segment at the point of tangency.. |
Correct Ans Provided: B
