Why is a straight angle 180 degrees?

In Maths, a straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line. … Hence, the two rays of the 180-degree angle are subtended towards the opposite direction, where the rays are joined to each other at endpoints.
