The first positive angle between the initial and terminal arm of an angle in standard position is called the​

Answer 1

Answer:

The initial arm of an angle rotates to its terminal position, either in a positive, counterclockwise direction or a negative, clockwise direction. The principal angle is the first positive angle less than 360°.

Answer 2

The positive angle formed when an angle is in a standard position is called principal angle.

An angle is formed at the point where two or more lines meet.  And it is said to be in a standard position if its edge is located at to the origin with its initial arm in line with the horizontal axis. The initial arm of an angle is the side with which the angle is measured from, while the terminal arm is the side on which the measure of an angle terminates. Thus, angles are normally measured from there initial arm to the terminal arm.

Therefore, the first positive angle formed between the initial and terminal arm of an angle in a standard position is usually called the principal angle.
