What is 180 Degree Angle?

180-degree angle, also known as a straight angle, is the result of two lines or rays extending from a common point in opposing directions to produce an exact straight line.

It appears as a straight line without any bends or curves. A 180-degree angle is the biggest angle that may be created in Euclidean geometry because its measure is exactly 180 degrees.

180 Degree Angle Definition

180 degree angle is defined as an angle that is created when two rays, lines, or line segments extend in opposite directions from a single endpoint, called the vertex, to produce a straight line.

The measure of a 180-degree angle is precisely 180 degrees, indicating a half-circle.

180 Degree Angle Name

180-degree angle is called a straight angle because of its ability to form a straight line. Straight angle refers to the fact that it does not bend or deviate, forming a complete half-circle or a full turn.

180 degree angle is made up of rays or lines that are aligned in opposing directions forming a straight line, hence it is called a straight angle.
