When the beginning ray of the angle is on the x-axis.
The angle function in standard position is typically measured from the positive x-axis in a counterclockwise direction. An angle is in standard position when its vertex is at the origin of a coordinate plane, and its initial side lies along the positive x-axis. The terminal side of the angle is determined by the angle's measure, and it can be positive or negative, depending on the direction of rotation.
On a Cartesian plane (or one using polar coordinates), the vertex of the angle must be at the origin and one of the rays must lie along the positive x-axis (point towards the East).
A reference angle is the acute angle formed by the terminal side of an angle and the x-axis in standard position. It is always measured as a positive angle and is typically between 0 and 90 degrees. Reference angles are useful in trigonometry for simplifying calculations and understanding the properties of angles in different quadrants. For any angle θ, the reference angle can be found using specific formulas depending on the quadrant in which θ lies.
The terminal side of an angle is the line that extends from the vertex of the angle, typically measured in standard position where the initial side lies along the positive x-axis. As the angle opens, the terminal side moves counterclockwise for positive angles and clockwise for negative angles. The terminal side can be located in any of the four quadrants of the Cartesian plane, depending on the angle's measure.
An angle of 168 degrees is classified as an obtuse angle, as it is greater than 90 degrees but less than 180 degrees. It is often found in various geometric contexts and can be used in applications such as architecture, design, and engineering. In standard position, it is located in the second quadrant of the Cartesian plane.
It is angle.

Quadrantal angle
On a Cartesian plane (or one using polar coordinates), the vertex of the angle must be at the origin and one of the rays must lie along the positive x-axis (point towards the East).
Any angle (in standard position) between zero and 90 degrees is in the first quadrant.
The starting point of what?When an angle is in standard position, the initial arm is the positive x-axis, and the angle is measured in a counter-clockwise direction.If this is not your question, please clarify and ask the question again. :-)
When a patient is standing with eyes and feet forward, she is said to be in the anatomical position. This standard position is characterized by the body being upright, facing forward, with arms at the sides and palms facing forward. It serves as a reference point for anatomical terminology and orientation.
An angle measuring 90 degrees is said to be a "right" angle.
They are equal angles.
On a standard wall clock, 4:00 is an obtuse angle.
There is no standard angle for a battlefield (not battlefeild!) since they come in all shapes.
A standard sheet of paper has a right angle at each corner.
