Answer: b) straight

Step-by-step explanation:

Let's go through each option:

a) acute: An acute angle is an angle that measures less than 90°.

b) straight: A straight angle is an angle that measures exactly 180°. It forms a straight line.

c) right: A right angle is an angle that measures exactly 90°, forming a perfect L-shape.

d) obtuse: An obtuse angle is an angle that measures more than 90° but less than 180°.

So, the correct answer is b) straight because a 180° angle forms a straight line.
