• segment BC

• segment AC

• segment DC

Given the figure ,find the value of x.

• 3

• 6

• 9

Use the figure , if SL = 12 , DL = 18 , and SU = 16, find SB.

• 28.67

• 22.5

• 18

• 12

What theorem if two chords intersect in the interior of the circle, then the product of the lengths of the segments of the chord is equal to the product of the lengths of the segments of the other chord.

What is the definition of a secant?

• A line segment whose endpoints are on the circle.

• A line that intersects a circle in one point.

• A line that intersects a circle in two points.

• A line segment which intersects the circle at the point of secancy.

Which is secant?

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

In a circle, if a diameter bisects a chord (that is not a diameter), then:

• it is a secant

• it is parallel to the chord

• it is perpendicular to the chord

• it is just shaking out the sillies

A ____ is a line, ray, or segment that intersects a circle at two points.

• Tangent

• Secant

• Radius

• Arc
