180 degrees is a straight line
Supplementary angles add up to 180 degrees
The question probably refers to the internal angles of a triangle which total 180° . Also, the angle at the centre of a circle and subtended by half the circle is 180°.
A full circle is 360 degrees. 180 degrees is a half circle. 90 degrees is a quarter circle.
Semi-circle.
An arc that measures exactly 180 degrees is called a semicircle. In a circle, a semicircle is formed when an arc spans half of the circumference, which corresponds to 180 degrees. Semicircles are important in geometry and trigonometry, often used in calculations involving angles and circles.
It is half the circumference of a circle that has an arc of 180 degrees
