One side of the angle is always fixed along the positive x-axis - that is, going to the right along the axis in the 3 o'clock direction (line BC). This is called the initial side of the angle. The other side of the angle is called the terminal side.

- Terminal Side of an Angle
An angle is in standard position in the coordinate plane if its vertex is located at the origin and one ray is on the positive x-axis. The ray on the x-axis is called the initial side and the other ray is called the terminal side.
10 paź 2024 · The initial side of an angle theta drawn in angle standard position is the side lying on the positive x-axis.
The “initial side” refers to the starting position of an angle in the coordinate plane. In trigonometry, angles can be measured in standard position, which means they start from the positive x-axis and rotate counterclockwise. To determine the initial side of an angle, imagine a coordinate plane.
In this position, the vertex (B) of the angle is on the origin, with a fixed side lying at 3 o'clock along the positive x axis. The other side, called the 'terminal side' is the one that can be anywhere and defines the angle.
The side that is fixed along the positive x axis (BC) is called the initial side. To make the angle, imagine of a copy of this side being rotated about the origin to create the second side, called the terminal side.
In mathematics, the term "initial side" refers to the starting position or reference point for measuring angles in the Cartesian coordinate plane. It is
