a straight line
180 is half of 360 therefore 180 is half of a cirlce because 360 is a circle
The whole measurement of a angle.
A 180-degree arc is also called a half-circle.
A 180-degree angle is a straight line, so you could pretty much say the edge of anything (such as a book, ruler, paper, etc.).
A 180 degree arc
Cut it in half
a straight line

No. You have to cross 360 degrees of meridian for a great circle, so 180 degrees East plus 180 degrees West around the equator will form a great circle.
pi is not equl to 180 degree but it is often simplified as 22/7, it is used to calculate area of circles,etc A circle is 360 degree
A 180-degree arc is also called a half-circle.
180 degrees, if you mean a half circle
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
A 180-degree angle is a straight line, so you could pretty much say the edge of anything (such as a book, ruler, paper, etc.).
a triangle= 180 degrees circle= 360 degrees that is all I know
