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.

What figure is formed by a terminal side and an initial side?
An angle on the coordinate plane
A is an angle whose sin is 37 and whose secant is negative Its vertex is the origin and one side is the positive x axis. What quadrant does the terminal side of the angle reach?
There is no such angle, since the sine of an angle cannot be greater than 1.
How do you convert angle degrees to mm offset if you know the length of the side?
This question is ambiguous. If you have an original side, and you know the terminal (final) side, and you know the terminal angle (between the two sides), then there's really not that much more. For rectangular coordinates (x and y) of offsets, use sines and cosines. Vertical offset is (terminal sidelength)*sin(DEGREE MEASURE) Horizontal offeset is (terminal sidelength)*cos(DEGREE MEASURE)
What is the reference angle for 243 degree?
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 243 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it. Thus, the reference angle is 243° - 180° = 63°.
Why is ninety degree not taken as the angle of reference?
in trig a reference angle is ised to create a reference triangle in the first quadrant by using any point except the origin that lies on the terminal side of the ref. angle and drawing a perpendicular to the x-axis. for 90 degrees the terminal side is the y-axis and the perpendicular would not create a triangle, but just retrace the y-axis.
What is the terminal side of an angle?
a ray of an angle that rotates around the vertex
What is the angle when the terminal side of an angle in standard position lies along one of the axes?
Quadrantal angle
