EXAM QUESTIONS AND ANSWERS
GRADED A+ 2025/2026
Calculate a back bearing for a line with a bearing of S 82° 20' E - ANS - N 82 20' W
What are the effects on the latitude and departure components of an ending point's
coordinates when a line starts at a beginning point heading in a northeast direction and ends at
the ending point? Pick the correct selection from the following choices. - ANS - Increase both
latitude and departure
In construction, __________ is used to establish control around the job site to lay out the
structures. - ANS traversing
The method of surveying measurement determines the angles and distance between a series of
points. These measurements are used to calculate the positions of the points. This series of
points are used to establish a grid system and is called - ANS traverse
vary from 0 to 90° and require two letters and a numerical value ( N 60° E, S 30° W, etc.). -
ANS bearings
The two most basic tasks of coordinate geometry calculations are determining the distance and
direction between 2 points. This calculation is known as - ANS Inversing

, It is standard practice to turn __________ angles clockwise from the backsight point to the
foresight point. Therefore, when traversing around a polygon, it is convenient to do so in a
counterclockwise manner. - ANS Interior
If the traverse is being run around a job site and is a closed polygon, __________ angles are
typically measured. - ANS Interior
Calculate a back azimuth for a line with an azimuth of 90º. - ANS 270 degrees
The primary use of coordinates on the construction site is to use them for directions when
explaining how to get to a site. - ANS false
In high-rise construction, which of the geometric relationships within an instrument is most
important for plumbing the structure? - ANS - The horizontal axis should be perpendicular to
the vertical axis
Determine relationships in triangles using the angles and sides - ANS - Trigonometry
Description of the combined mathematical processes of plane geometry, trigonometry, and
coordinate systems that surveyors use to determine coordinates and layout data - ANS COGO
The mathematics that deals with the relationships, properties, and measurements of solids,
surfaces, angles, and lines. - ANS Geometry
Fundamental knowledge for solving equations - ANS Algebra
