An angle with a degree measure more than 90 degrees but less than 180 degrees is known as what?

• A. Acute angle
• B. Obtuse angle
• C. Straight angle
• D. Full angle

Answer: (B)

An angle that measures more than 90 degrees but less than 180 degrees is defined as an obtuse angle. This classification is based on the specific ranges of angle measures in geometry. An obtuse angle exceeds the size of a right angle (which measures exactly 90 degrees) and is less than a straight angle (which measures exactly 180 degrees). This characteristic sets it apart from acute angles, which measure less than 90 degrees, and straight angles, which are exactly 180 degrees. A full angle, also known as a complete revolution, measures 360 degrees. Understanding these distinctions is crucial in geometry because it helps categorize angles based on their measures, which is foundational knowledge in the study of various geometric principles and applications.
