## Trigonometry (10th Edition)

1. 180-270 degrees are in the third quadrant. Therefore, 180$^{\circ}$$\leq234^{\circ}$$\leq$270$^{\circ}$ it's in the third quadrant 2. Coterminal angles are always in the same quadrant with original angle, because of full resolutions (2$\pi$) 234° + 360° = 594° 234° - 360° = -126°
