Two chords of the circle intersect and divide each other into two line segments. The segment of the first chord are 6 cm and 3 cm long. One segment of the second chord is 2 cm. How long is the remaining segment?
There is a theorem that says if you multiply the two sections of one chord you will get the same answer if you multiply the two sections of the other chord.
If you call the missing section 'x', then you have 2·x = 3·6 ---> 2x = 18 ---> x = 9.
