II. Write c_{1} the statement is correct and I if incorrect.

6. The point of intersection of the line and the circle is called the point of tangency.

7. External secant segment is a part of a secent segment that is outside the circle.
8. To find the area of a sector of a circle, get the difference of the ratio and the area of a circle.
9. tf a line is perpendicular to the radius at a point of a circle, then the line is tangent to the circle.
10. If a secant and a tangent intersect in the exterior of the circle, then the angle formed is one-half the sum of the measures of the intercepted arcs.

5/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.145/4 pi s³ when s = 20 and pi = 3.14
