C. DIRECTION: Tell whether the statement is TRUE OR FALSE. Write your answer before the number.

1. A central angle is an angle whose vertex is the center of the circle.

2. A semicircle is the union of the endpoints of a diameter and all points of the circle that lie on one side of the diameter.

3. The degree measure of a minor arc is equal to the degree measure of its central angle.

4. The degree measure of a major arc is equal to 180 minus the degree measure of its related minor arc.

5. The degree measure of a semicircle is 360.

6. The measure of an arc formed by two adjacent, non-overlapping arcs is the sum of the measures of the two arcs.

7. In the same circle or in congruent circles, arcs that have the same measure are congruent arcs.

8. If two chords of a circle or of congruent circles are congruent, then the corresponding minor arcs are congruent.

9. An inscribed angle is an angle whose vertex lies on the circle and whose sides contain chords of the circle.

10. A chord is a segment whose endpoints both lie on the circle.
