What does it mean for an angle to be in standard position?

Standard Position of an Angle - Initial Side - Terminal Side. 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.

Just so, what is the terminal side of an angle in standard position?

In trigonometry an angle is usually drawn in what is called the "standard position" as shown on the right. 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.

What is the angle of trigonometry?

Angle (Trigonometry) Definition: An angle which has its vertex at the origin, and one side lying on the positive x-axis. It can have a measure which positive or negative and can be greater than 360°. Try this: Adjust the angle below by dragging point A and see how the angle ABC behaves.

What is a positive angle?

Negative Angles. Negative angles are a way of measuring an angle from a different direction. A positive angle is created by rotating counter-clockwise around the origin of a coordinate system, starting at the x-axis (the horizontal axis) and proceeding through the quadrants in the order I, II, III, IV.
