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:

Learn what a 180 degree angle is, how to draw it, and how to find it in everyday life. Explore the types of angles, solved examples and frequently asked questions about straight angles.
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 is 180 degrees. This is a straight angle. A straight angle changes the direction to point the opposite way. Sometimes people say "You did a complete 180 on that!" ... meaning you completely changed your mind, idea or direction.
Angles on one side of a straight line always add to 180 degrees. Example: 30° + 150° = 180°. When a line is split into 2 and we know one angle, we can always find the other one.
