Acute angles are less than \( 90^{\circ} \). Therefore, the acute angles from your list are \( 25^{\circ} \) and \( 15^{\circ} \). Obtuse angles are between \( 90^{\circ} \) and \( 180^{\circ} \), so \( 91^{\circ}, 170^{\circ}, 144^{\circ}, 88^{\circ}, 70^{\circ}, 111^{\circ} \) fit this category. Lastly, reflex angles are greater than \( 180^{\circ} \) but less than \( 360^{\circ} \), meaning \( 200^{\circ}, 150^{\circ}, 300^{\circ}, 210^{\circ}, 188^{\circ}, 250^{\circ} \) belong here. So here's the breakdown: - Acute: \( 25^{\circ}, 15^{\circ} \) - Obtuse: \( 91^{\circ}, 170^{\circ}, 144^{\circ}, 88^{\circ}, 70^{\circ}, 111^{\circ} \) - Reflex: \( 200^{\circ}, 150^{\circ}, 300^{\circ}, 210^{\circ}, 188^{\circ}, 250^{\circ} \)
