What is a straight angle?
A straight angle is 180 degrees when measured. The figure above illustrates a straight angle or a 180-degree angle. You can see that it is just a straight line because the angle between its arms is 180 degrees. Reflex Angle. Since this measurement is less than 90 degrees, the arms form an acute angle. But what about the angle on the other side?
The 180-degree angle is a straight angle and forms a straight line. It is exactly half of the full angle (360-degree angle). Learn about the 180-degree angle, its construction, properties in this article.
What Is a 180 Degree Angle? The 180 degree angle is an angle that forms a straight line. The 180 degree angle in radians is or about 3.14 radians. You can see that the straight line is formed when the two arms of the angle (BA and BC) are opposite rays. The two arms extend in the opposite directions.

A straight angle, also known as a 180-degree angle, is defined as an angle that measures exactly 180°. It forms a straight line whose arms lie in opposite directions from the vertex. It is thus also called ‘flat angle’ and is represented using the symbol π (pie). A few more examples of straight angle are shown below:
Hands of a clock showing 6’ o clockCorner of an inclined plane of a staircaseThe angle in a see-sawA straight angle: 1. Can be formed by rotating one arm of an angle by 180° with respect to the other 2. Can be formed by joining two right angles 3. Measures exactly half of a revolution
A straight angle measures 180° and looks like a straight line, therefore, it is a mathematical way of expressing a straight line. It is an angle whose arms lie in opposite directions from the vertex and they join together to form 180°.
3 days ago · Straight Angle: The straight angle can be defined as an angle whose measure is 180 degrees. Its straight angle looks like a straight line. They are collinear and opposite rays. When we keep a thin book open, we can see that the angle formed between the two pages is an example of a straight angle.
In geometry, a straight angle is defined as an angle that is equal to 180 degrees. The reason it is called a straight angle is because it appears as a straight line. In other words, it is an angle whose sides lie in opposite directions from the vertex in the same straight line.
