Which statement defines a straight angle?

Explanation:
A straight angle is an angle that measures 180 degrees, formed when two opposite rays share a common endpoint and lie on the same straight line. This exact measure creates a line, with no bend. That’s why the statement defining a straight angle is 180 degrees. The other descriptions refer to different angle types: less than 90 degrees is an acute angle, exactly 90 degrees is a right angle, and more than 180 degrees is a reflex angle.
