Question

what does a worker use to orient themselves to a project when reading plans?
north arrow
compass rose
front elevation
gps coordinates

Explanation:

In construction plans, the north arrow is a common element used to indicate the orientation of the project. It helps workers understand the direction (north - south - east - west) of the building or structure relative to the actual compass directions. A compass rose is more commonly found on maps (not specifically on construction plans). The front elevation is a view of the front of a building (shows height, windows, doors etc., but not orientation). GPS coordinates are for location (latitude and longitude) not orientation on a plan.

Answer:

north arrow
