question 74 of 100 - multiple choice

theodolites are commonly used to establish angular offset lines and _ lines?

a straight

b flat

c bowed

d curved

Explanation:

Identify the function of a theodolite

A theodolite is a precision optical instrument used for measuring angles in the horizontal and vertical planes. In industrial alignment and surveying, it is used to establish highly accurate, straight lines of sight (collimation lines) and angular offsets.

Evaluate the given options

• (A) straight: Theodolites project a precise, straight line of sight over distances.
• (B) flat: While they can measure horizontal planes, "flat lines" is not the standard terminology for optical lines of sight.
• (C) bowed: Optical lines of sight do not curve or bow.
• (D) curved: Light travels in straight lines, so optical instruments establish straight reference lines.

Answer:

• (A) straight (Correct answer)
• (B) flat
• (C) bowed
• (D) curved
