A 180-degree arc is also called a half-circle.
A major arc
A minor arc.
With a central angle of 180° it is a straight line and so the arc is a semi-circle
There is no such thing as one degree of minute.There are 60 minutes of arc in one degree of arc and 60 seconds of arc in one minute of arc
Just "degree", not "arc degree". A degree has 60 minutes; therefore, to convert from degrees to minutes, you multiply by 60.

Half the circumference of a circle has an arc of 180 degrees
It is half the circumference of a circle that has an arc of 180 degrees
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
1 degree = 60 minutes of arc 1/2 o = 60/2 ' = 30'
A circle subtends 360° . Therefore. if the angle subtended at the centre of a circle by an arc is greater than 180° then this is the major arc. By comparison, the minor arc will subtend an angle less than 180°
An arc whose measure is less than 180 degrees is called a Minor Arc.
A 180-degree arc is also called a half-circle.
