Question

question 26 (1 point)
the first positive angle between the initial and terminal arm of an angle in standard position is called the

a) co - related angle
b) related angle
c) principal angle
d) acute related angle

Explanation:

In the context of angles in standard position, the principal angle is defined as the first positive angle between the initial and terminal arm. The term "co - related angle" is not a standard term in this context. A "related angle" (also known as a reference angle) is the acute angle that the terminal side makes with the x - axis. An "acute related angle" is not the correct term for the first positive angle between the initial and terminal arm.

Answer:

C. principal angle
