What is a straight angle?

An angle that measures exactly 180 degrees
An angle that measures less than 90 degrees
An angle that measures more than 180 degrees
An angle that measures 360 degrees

The correct answer is: An angle that measures exactly 180 degrees

A straight angle is defined as an angle that measures exactly 180 degrees. This means that when two rays emerge from a single point and point directly opposite each other, they create a straight line, which is represented by a 180-degree angle. This is a fundamental concept in geometry, distinguishing a straight angle from other types of angles, like acute angles (which are less than 90 degrees) and reflex angles (which are greater than 180 degrees but less than 360 degrees). A straight angle serves as a key reference point when discussing the measurement and classification of angles.
