The terminal side of a
angle in standard position is the negative y-axis.
Explicación
## Step 1In trigonometry, an angle in standard position is defined as an angle whose vertex is at the origin and its initial side lies along the positive x-axis. The terminal side of the angle is determined by the rotation of the angle from the initial side.## Step 2A negative angle indicates a clockwise rotation from the initial side. ## Step 3A
angle means a clockwise rotation of 90 degrees from the positive x-axis. ## Step 4After a 90-degree clockwise rotation, the terminal side of the angle would be along the negative y-axis.
