An arc whose measure is less than 180 degrees is called a Minor Arc.
Major Arc
A major arc must measure over 180 degrees, or pi radians
Arc length = pi*r*theta/180 = 17.76 units of length.
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°
A minor arc.
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
semicircle
a minor arc measures less than 180 degrees...
SEMI-CIRCLE
An arc whose measure is less than 180 degrees is called a Minor Arc.
Minor arc
It could be either acute or obtuse.
A radian measures the degree of the arc. For instance, π radians is 180°. Then, the arc with π radians measures 180°.
The complete arc of a semicircle is 180 degrees
