  Section 1 - Review Exercise
 
1. A section corner has been determined lost, but corners have been identified in all four directions. What method should be used to restore that lost corner?
Choice 1 a. single proportion measure
Choice 2 b. double proportion measure
Choice 2 c. two way proportion
Choice 2 d. four way record directions
2. Lengths of proportioned lines are comparable only when reduced to their
Choice 1 a. sea level distance.
Choice 2 b. measured slope distance.
Choice 2 c. true line length.
Choice 2 d. cardinal equivalents.
3. Choose the formula that shows proportion "P" determination.
Choice 1 a. Total Ret./Total Rec. = P/Record
Choice 2 b. Total Rec./Total Ret. = Record/P
 
4. Here is a lost corner with identified corners in four cardinal directions. The record was run with ties to the known corners at the end of the resurvey run. Compute the proportional courses, bearing and distance, for C2. -- This two part question is worth 40 pts.

Bearing
Choice 1 a. N 01° 15' 20" W
Choice 2 b. Bearing = N 0° 11' 15" W
Choice 3 c. Bearing = N 01° 15' 20" E
Choice 4 d. Bearing = N 0° 11' 15" E

Distance
Choice 4 a. Distance = 40.00
Choice 4 b. Distance = 40.865
Choice 4 c. Distance = 40.970
Choice 4 d. Distance = 40.790
