Geo B Mod 4 Circle Theorems Lesson #2

By Denise Wright

If two chords of a circle intersect, then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.

When they intersect OUTSIDE the circle

• a is the outside, (a+b) is the whole

• c is the outside, (c+d) is the whole

• outside(whole) = outside(whole)

Secant Product Theorem

If two secants intersect in the exterior of a circle, then the product of the lengths of one secant segment and its external segment equals the product of the lengths of the other secant segment and its external segments.

The whole thing times the top part

(4+2)*4=(3.5+x)*3.5

What if a is the outside and the whole?
