On the segment AB equal to 20 cm, point K is chosen so that AK = 16 cm and point M so that BM

On the segment AB equal to 20 cm, point K is chosen so that AK = 16 cm and point M so that BM = 12 cm. The segment K M (in cm) is equal to?

First action.

We need to find the total length, presented in the condition of the task, of the AK and VM segments:

16 + 12 = 28.

Second action.

We need to compare the resulting total length with the length of the initial segment, which is the segment AB:

20 <28.

That is, the segments AK and BM partially contain each other.

Third action.

We find out how many centimeters in this case the length of the designated KM segment will be equal to:

28 – 20 = 8.

Answer: The length of the designated KM segment will be 8 cm.
