A chord is the part of a circle defined by two endpoints.
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.

Semi-circle
Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.
Sector
They are two sections of the circumference of the circle.
Measure the distance between the two end points!
Not necessarily.
