A (1)________ is defined as the set of all coplanar points equidistant from a fixed called the (2)_________. The segment from the center to any point in the circle is the (3)_________. A segment that crosses the circle by passing through the center of the circle is called (4)________. A (5)________ of a circle is a segment whose endpoints lie on the circle. The (6)_________ is a line intersects a circle in two points, while a (7)_______ is a line intersects the circle at one point. The point of intersection is called (8)________. A circle divides the plane into three parts. the (9)_________ or points inside the circle, the (10)________ or points outside the circle and the points on the circle. The two distinct points on a circle divide the circle into two parts called arcs. If the endpoints of an arc are the endpoints of a diameter, then the arc is a (11)________. If an arc whose measure is less than 180° that arc is called (12)________ while an arc whose measure is greater than 180° is the (13)________. Arcs are measured by their corresponding (14)_________ and the (15)_________ of a circle is formed by two chords that have a common endpoints on the circle and the measure is half of its intercepted arc.
