A straight angle is a type of angle in geometry that measures exactly 180 degrees
A straight angle is a type of angle in geometry that measures exactly 180 degrees. It is formed by a straight line that consists of two opposite rays or line segments.
In simpler terms, a straight angle looks like a straight line and has no curvature or bending. It is a fully open angle that forms a straight line. The two rays or line segments that form the straight angle are collinear, meaning they lie on the same line.
Since a straight angle measures 180 degrees, it is considered the largest possible angle in geometry. Any angle larger than 180 degrees is not considered a straight angle. A straight angle can also be categorized as a reflex angle since it exceeds the size of a typical angle.
To illustrate, imagine a line segment AB. If you extend the line segment further on both ends, forming a line, you would have a straight angle where the rays or line segments would be AB and BA. The vertex of a straight angle is the point where the two rays or line segments meet.
In real-life examples, a straight angle can be seen in a variety of contexts. For instance, when you hold up a ruler horizontally, the line it forms with the ground or table represents a straight angle. Similarly, when you extend your arms outwards and form a straight line at shoulder level, that is also an example of a straight angle.
In summary, a straight angle is a mathematical concept that represents a fully open angle measuring 180 degrees. It forms a straight line and is considered the largest angle in geometry.
