# Arc of the Circle

#### definition

Arc of the Circle: A chord divides the circumference of a circle into two parts and each part is called an arc.

Minor Arc: The arc which is less than the semicircle is called minor arc.

Major Arc: The arc which is greater than the semicircle is called major arc.

# Arc of the Circle:

• An arc is a part of the circumference of a circle.

• A chord divides the circumference of a circle into two parts and each part is called an arc.

• In the figure, given above, chord PQ divides the circumference into two unequal arc PRQ and arc PQ.

• The arc which is less than the semicircle is called minor arc.

• The arc which is greater than the semicircle is called major arc.

• If two arcs of a circle have common endpoints and the arcs make one complete circle, the arcs are said to be corresponding arcs. Here, arc PRQ and arc PQ are mutually corresponding arcs.

• In the figure below, chord AB is a diameter of the circle. The diameter gives rise to two equal arcs. They are called semicircular arcs.
