Which elementary surveying instrument is specifically used by a surveyor to set out perpendicular offset lines at right angles (90∘90^\circ) from a baseline?

  1. Cross-staffCevap
  2. B
    Clinometer
  3. C
    Prismatic compass
  4. D
    Ranging pole

Cevap

Cross-staff
The cross-staff is specifically constructed with sight lines fixed at right angles (90∘90^\circ), enabling a surveyor to quickly and accurately erect perpendicular offset lines from a main baseline.

Adım Adım Çözüm

1
Identify the specific function required in the question stem.
The requirement is an instrument used to establish perpendicular (90∘90^\circ) offset lines from a survey baseline.
Different surveying tools are designed for specific geometric tasks in the field.
2
Match the requirement with the correct elementary surveying tool.
The cross-staff contains fixed sighting slots set at 90∘90^\circ angles to easily lay out perpendicular lines.
Understanding fundamental instrument designs allows accurate identification of their field functions.
