Question

an angle measuring between 90° and 180° is called ______. a. acute b. small c. straight d. obtuse

Explanation:

To solve this, we recall angle definitions:

• Acute angles are less than \(90^\circ\).
• "Small" is not a standard angle classification term.
• A straight angle is exactly \(180^\circ\).
• An obtuse angle is defined as an angle measuring between \(90^\circ\) and \(180^\circ\).

So the correct option is D.

Answer:

D. obtuse
