An error was made in the problem statement. The given triangle is not isosceles, but equilateral.
1. Calculate the length of each side of a given triangle, taking into account that their sum is 24 centimeters ::
AB = BC = AC = 24: 3 = 8 centimeters.
3. The middle line of the triangle MK has a length half as long as the length of the parallel side of the AC:
MK = AC: 2 = 8: 2 = 4 centimeters.
Answer: MK = 4 centimeters.
