__B__ 3) Common Internal Tangent

__F__ 4) Common External Tangent

__H__ 5) Center

__A__ 6) Radius

__E__ 7) Diameter

__C__ 8) Secant

Find the indicated measures of circle E.

9) ____60º______

10) ____55º______

11) ___235º______

12) List the three numbered angles in order from

the smallest angle to the largest angle.

3, 1, 2

13) Give an example of a shape that can always be inscribed in a circle. Explain how you know that this will always be true.

Answers will vary. Remember that opposite angles must be supplementary.

14) One theorem that we discussed says that “If a right triangle is inscribed in a circle, then the hypotenuse is a diameter of the circle.” Explain why this is true. (Drawing a picture may help.)

Answers will vary. You should discuss what you know about the relationships between inscribed angles and the arcs they intercept.

Find the value of x.
