Diameter Chord Theorem

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

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

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

In a circle, if a diameter is is perpendicular to a chord, then:

• it bisects the chord

• it bisects the corresponding arc

• it bisects BOTH the chord and its arc

• none of these answers are correct

Determine the value of x and y.

In the diagram, the diameter of the circle is perpendicular to a chord. Solve for the value of "x" and "y"

• x = 4, y = 5

• x = 3, y = 7

• x = 7, y = 3

• x = 6, y = 9

In the diagram, the diameter of the circle is perpendicular to a chord. Solve for the value of "x" and "y"

• x=4, y=5

• x=3, y=7

• x=7, y=3

• x=6, y=9
