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 and it looks like a horizontal line. In other words, it is a line that is completely straight and does not curve or bend at any point.
A straight angle can also be thought of as two opposite rays or line segments that share the same endpoint and form a straight line. The two rays that form a straight angle are called the arms or sides of the angle, and the common endpoint is called the vertex.
Due to its measurement of 180 degrees, a straight angle is the largest possible angle in Euclidean geometry. Any other angle that measures less than 180 degrees is considered to be an acute angle or an obtuse angle.
Some real-life examples of straight angles include the corners of a rectangular or square shape, the edges of a ruler or paper, or the intersection of two perpendicular lines. It is important to note that even though a straight angle measures 180 degrees, it does not indicate any information about the shape or size of the lines or objects that form it.
