What is NOT a side of the navigational triangle used in sight reduction?
AI Explanation
The correct answer is B) Altitude.
The navigational triangle used in sight reduction consists of three sides: colatitude, zenith distance, and polar distance. Altitude is not one of the sides of the navigational triangle, as it is a different element used in the celestial navigation process. Altitude represents the angular height of a celestial body above the horizon, while the sides of the navigational triangle are used to calculate the other variables needed to determine the position of the observer.
The other answer choices (A, C, and D) are all correctly identified as sides of the navigational triangle, but altitude is not one of them.
