The line containing points E and G is a diameter. It ______ chord DF.Answer choice:A)never crossesB)intersects the endpoint ofC)runs parallel toD)bisects

Solution:
Concept:
If a diameter of a circle bisects a chord, then it must be perpendicular to the chord. If a diameter of a circle is perpendicular to a chord, then it bisects the chord. If two chords are congruent, then the center is equidistant from the two chords.
[tex]diameter=line\text{ }connecting\text{ }E\text{ }and\text{ }G[/tex]The chord given in the question is
[tex]chord=DF[/tex]Hence,
The final answer is
It BISECTS chord DF
OPTION D is the right answer
