Question: 1 / 400

How many degrees are in a straight angle?

90°

180°

A straight angle is defined as an angle that measures exactly 180 degrees. This means it represents a half-turn on a circle, creating a linear alignment of two rays extending in opposite directions. Understanding this concept is fundamental in geometry, as it helps differentiate between various types of angles.

In terms of the provided choices, while 90 degrees refers to a right angle, which is a quarter turn, and 270 degrees corresponds to three-quarters of a turn, 360 degrees indicates a complete turn. Therefore, the only correct representation of a straight angle among the options is 180 degrees. This reinforces the idea that a straight angle perfectly bisects the circular path of a full rotation.
