Chord Properties

A chord is any line in a circle

• True

• False

If $\overline{BD}\cong\overline{DC}$ and  $\overline{EF}\ \perp\ \overline{BC}$ , what conclusions can say about  $\overline{EF}$  ? 
(Hint: Use Chord Theorem #2)

•  $\overline{EF}$  is the radius of circle A

•  $\overline{EF}$  is a secant line of circle A

•  $\overline{EF}$  is the diameter of circle A

•  $\overline{EF}$  is the tangent line of circle A
