What is the range of degrees for an acute angle?

• A. 0 to 45
• B. 45 to 90
• C. 0 to 90
• D. 90 to 180

Answer: (C)

An acute angle is defined as an angle that measures greater than 0 degrees but less than 90 degrees. This means that any angle within those limits, such as 1 degree, 45 degrees, or even 89 degrees, qualifies as acute. The range of degrees for an acute angle thus includes all values starting just above 0 and extending up to, but not including, 90 degrees. Since option C specifies the range from 0 to 90 degrees, it accurately captures the definition of an acute angle. In contrast, other ranges provided do not fit this definition. For instance, the choices that mention 90 degrees and above include right angles and obtuse angles, which do not classify as acute. Therefore, understanding the basic definitions of angles allows us to confirm that the correct range for acute angles aligns with the provided answer.
