Angle is in standard position of the vertex is at the starting point and the one ray is on the positive x axis. Ray on the x-axis is called the start and other radiation is the Terminal.
Angle in the standard position of the vertex is the starting point. And Ray is on the positive x-axis is called the x-ray and other radiation from the terminal is terminal.
The angle position standard of vertices at the beginning and ray one on the axis X positive ray axis on X called the start and radiation. It is the terminal.
