In geometry, an arc is a curved portion of a circle. It is defined by two endpoints and the points along the circumference of the circle that lie between the endpoints. The measure of an arc is typically given in degrees.
The line passing through the center of a circle with two endpoints on the circle is the circle's diameter.

A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.

Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.
An arc is a portion of a curve defined by two endpoints and the points along the curve connecting them. It is a section of a circle's circumference or any other curved shape. The shape of an arc resembles a segment of a curve or part of a circle.

They are two sections of the circumference of the circle.
