Which statements accurately describe standard position angles? Select all that apply.

Question

A) Every standard position angle must have both its initial and terminal side on the positive side of the x-axis.

B) In standard position, the cosine of θ represents the y-coordinate, and the sine of θ represents the x-coordinate of the point where the terminal side of the angle intersects with the unit circle.

C) To determine the point of intersection, (x,y), the angle must first lie in standard position.

D) Every standard position angle must have its vertex at (0,0).

Answer 1

Definition:

An angle is in standard position if its vertex is located at the origin, and its initial side extends along the positive x-axis. Both A and D are characteristics of an angle in standard position but A is the best answer.
