Understanding Circles and Segment Lengths

What should you focus on when dealing with segments in circles?

• Circle diameters

• Angle measures

• Arc measures

• Segment lengths

When two segments meet outside a circle, what is the relationship between their outer parts and whole lengths?

• Outer part times whole length of one segment equals outer part times whole length of the other

• Outer part of one segment is half the whole length of the other

• Outer part of one segment equals the whole length of the other

• Outer part of one segment is double the whole length of the other

In the example problem, what is the whole length of the segment with an outer part of 3?

• x

• 3

• 3 + x

• 3x

What is the length of the tangent segment in the example problem?

• 3

• x

• 6

• 9

After solving the equation, what is the value of x in the example problem?

• 9

• 3

• 12

• 6
