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.

The initial side remains stationary while the terminal side rotates to form an angle. In standard position, the initial side lies on the positive x-axis. The measurement of angles starts from the initial side and moves counterclockwise for positive angles and clockwise for negative angles.
7 Νοε 2024 · In general, viewing an angle as the amount of rotation about the intersection point (the vertex) needed to bring one of two intersecting lines (or line segments) into correspondence with the other, the line (or line segment) being rotated about the vertex is thought of as the initial side.
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.
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.
The initial side, terminal side, and angle measure are all closely related in the context of angles. The initial side is the reference line from which the angle is measured, typically oriented in the positive horizontal direction.
5 Σεπ 2024 · The ray on the x-axis is called the initial side and the other ray is called the terminal side. If the terminal side of an angle lies "on" the axes (such as 0º, 90º, 180º, 270º, 360º ), it is called a quadrantal angle. The angle shown at the right is referred to as a Quadrant II angle since its terminal side lies in Quadrant II.
