It is an arc comprising half the circumference.
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
180 is half of 360 therefore 180 is half of a cirlce because 360 is a circle
The whole measurement of a angle.
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.).
One degree corresponds to approximately 0.0175 inches when measured along the circumference of a circle with a radius of one inch. This relationship is derived from the formula for arc length, where the arc length (in inches) equals the radius multiplied by the angle in radians. Since there are 360 degrees in a circle, one degree equals ( \frac{\pi}{180} ) radians, leading to the conversion. Thus, for practical purposes, one degree represents a very small distance along a circle's edge.
