Question

what kind of angle is this? right acute obtuse or straight

Explanation:

Step1: Recall angle definitions

• A right angle is $90^\circ$ (like a corner of a square).
• An acute angle is less than $90^\circ$.
• An obtuse angle is more than $90^\circ$ but less than $180^\circ$.
• A straight angle is $180^\circ$, forming a straight line.

Step2: Analyze the figure

The figure shows a straight line with an arrow on both ends, which represents an angle of $180^\circ$.

Answer:

straight
