1.18.9. Methods of theodolite traversing

Try these first

1. 1.

   What is a closed traverse?

   Hint

   Think about how it connects back to itself.

2. 2.

   What defines an open traverse?

   Hint

   Consider long routes that do not close.

3. 3.

   What is the angle sum of a closed traverse?

   • 180°
   • 360°
   • 540°

   Hint

   Think about how angles close up the loop.

4. 4.

   True or False: An open traverse can form a closed figure.

   • True
   • False

   Hint

   Consider the definition of an open traverse.

5. 5.

   If a closed traverse has angles of 70°, 110°, and 180°, determine the remaining angle and identify if it’s an interior or exterior angle.

   Hint

   Sum all angles of a closed loop and check for requirements of angle types.

6. 6.

   For an open traverse, if you measure two angles turning to the right at 40° and then to the left at 30°, what is the net deflection angle from your starting direction?

   Hint

   Keep track of the direction of angle turns while calculating.
