I. Circle Theorems: Write Korak if the statement is

correct, Chonga if wrong.

1. The measure of the central angle and its intercepted

arc are congruent.

2. If the intercepted arc is common, the inscribe angle

is half of the central angle.

3. The inscribed angle of a semi-circle is sometimes a

right angle.

4. The opposite angles in a cyclic quadrilateral are

complementary.

5. Tangent-chord angle is its intercepted arc.

6. Tangent-chord angle and the inscribed angle of its

intercepted arc are congruent.

7. The angle of two intersecting tangents/secants is

half of the difference of the intercepted arcs.

8. A diameter do not bisects a chord if and only if It is

perpendicular to the chord.

9. A tangent is always perpendicular to the

radius/diameter.

10. The segments of two intersecting tangents are

congruent.​
