180º
180º is a measurement of an angle
180º is a measurement of an angle. It represents a half-turn or a straight line. In geometric terms, a full circle is divided into 360º, and 180º corresponds to half of this circle. This measurement is often used in geometry, trigonometry, and other math disciplines to describe the size or rotation of angles.
To visualize 180º, imagine standing at a starting point and turning halfway around to face the opposite direction. This would be equivalent to making a straight angle, where the rays of the angle form a straight line.
In trigonometry, 180º is often used as a reference angle for determining the values of trigonometric functions. For example, the sine and cosine of 180º are both 0, while the tangent is undefined or infinite. These values are often memorized as part of the unit circle in trigonometry.
In summary, 180º represents a half-turn or a straight angle. It is a common measurement used to describe angles and has specific trigonometric values associated with it.
