Obtuse angles are ______.

Obtuse angles are ______.

• A. Acute
• B. Right
• C. Oblique
• D. Straight

Answer: (C)

Obtuse angles are larger than a right angle but smaller than a straight angle. They’re not acute, not exactly 90 degrees, and not 180 degrees. In many geometry terms, oblique angles describe angles that are not right angles, so an obtuse angle fits under that broader label. The other options don’t match because acute is <90, right is exactly 90, and straight is 180. So obtuse angles are oblique.
