Question

classify the angle.
acute right obtuse straight

Explanation:

Step1: Recall angle definitions

• Acute angle: Less than \(90^\circ\), greater than \(0^\circ\).
• Right angle: Exactly \(90^\circ\) (forms a square corner).
• Obtuse angle: Greater than \(90^\circ\), less than \(180^\circ\).
• Straight angle: Exactly \(180^\circ\) (a straight line).

Step2: Analyze the given angle

The angle in the diagram is clearly smaller than a right angle (less than \(90^\circ\)). So it fits the definition of an acute angle.

Answer:

acute
