Analysis
To determine which angle is in the first quadrant, we need to understand the definition of "standard position" and the layout of the coordinate plane:
1. Standard Position: An angle is in standard position if its initial side lies along the positive x-axis, and the angle is measured counterclockwise if it is positive and clockwise if it is negative.
2. Quadrants:
- Quadrant I: to
- Quadrant II: to
- Quadrant III: to
- Quadrant IV: to
