Decide if these angles are acute, obtuse, or right angles. All diagrams are drawn to scale. Homework Help ✎
Acute angle: An angle with a measure between (but not including) 0° and 90°.
Right angle: An angle measuring 90°.
Obtuse angle: An angle with a measure between (but not including) 90° an 180°.
To determine the type of angle, use a 90° angle as a reference point.
Since the angle is greater than 90°, it is obtuse.
