STRAIGHT ANGLE Meaning and
Definition
-
A straight angle is a geometric term used in mathematics to describe the relationship between two rays or line segments that are collinear and lie in opposite directions. It is a type of angle that measures exactly 180 degrees, forming a perfectly straight line. In other words, a straight angle is a flat angle, wherein the two arms or sides of the angle are co-linear and never intersect.
The straight angle is often denoted by a small line segment marking the vertex of the angle to differentiate it from other types of angles. It is considered the largest possible angle in geometry, as it stretches infinitely in both directions. Being a perfectly straight line, a straight angle can be represented in various ways, such as a horizontal line scribed on paper or a segment of a ray extending to the left or right.
The concept of a straight angle is fundamental in geometry and serves as a reference point for measuring other angles. It helps in understanding and classifying various geometric shapes and structures. For instance, if two straight angles meet at a common point, they form a complete revolution or a full circle, measuring 360 degrees. This understanding is crucial while studying angles, polygons, and other geometric figures.

Etymology of STRAIGHT ANGLE
The word "straight" in "straight angle" comes from the Old English word "streht", meaning "direct" or "not crooked". In geometry, a straight angle is an angle that measures exactly 180 degrees, forming a straight line. The term was first used in English in the 1570s to describe this type of angle. The word "angle" originated from the Latin word "angulus", which means "corner" or "a bending". Therefore, the term "straight angle" refers to an angle that does not bend or deviate from being a straight line.
