What is the relationship between the lengths of two intersecting chords in a circle?

• The lengths of the two chords are always equal.

• The lengths of the two chords are always different.

• The lengths of the two chords are irrelevant in a circle.

• Product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord.

What is the relationship between the lengths of two secant segments intersecting outside a circle?

• The product of the lengths of the two secant segments is equal to the product of the lengths of their external parts.

• The lengths of the two secant segments are always equal.

• The lengths of the two secant segments are always different.

• The sum of the lengths of the two secant segments is equal to the sum of the lengths of their external parts.
