The point K is given on the segment EF. The segment EK is 4 cm shorter than the segment EF. Find the length of the segment KF.
1. By the hypothesis of the problem, the segment EK is 4 cm shorter than the segment EF. Therefore, EF = EK + 4.
2. Point K lies on the segments EF. From this we can conclude that EF = EK + KF.
3. We got two equalities EF = EK + 4 and EF = EK + KF, from which we obtain KF = 4 cm.
Answer: KF = 4 cm.
