What is the measure of a straight angle?

  1. 90 degrees

  2. 180 degrees

  3. 270 degrees

  4. 360 degrees

The correct answer is: 180 degrees

The measure of a straight angle is indeed 180 degrees. A straight angle is formed when the two rays or lines extend in exactly opposite directions, creating a straight line. This means that the angle measures exactly half of a full rotation around a point. In contrast, a 90-degree angle represents a quarter turn, a 270-degree angle corresponds to three-quarters of a turn, and a 360-degree angle signifies a complete rotation. Thus, the defining characteristic of a straight angle is that it measures precisely 180 degrees.
