Question

classify the angle as acute, right, obtuse, or straight.
diagram: a straight line with a point g in the middle, arrows pointing left and right
choose the correct answer below.
○ a. straight
○ b. obtuse
○ c. right
○ d. acute

Explanation:

Step1: Recall angle definitions

• Acute angle: $0^\circ < \theta < 90^\circ$
• Right angle: $\theta = 90^\circ$
• Obtuse angle: $90^\circ < \theta < 180^\circ$
• Straight angle: $\theta = 180^\circ$

Step2: Analyze the given angle

The diagram shows a straight line with a point \( G \) in the middle, forming an angle of \( 180^\circ \), which matches the definition of a straight angle.

Answer:

A. straight
