Given a segment Ab = 16 cm. Point M is the midpoint of segment Ab, point k is the midpoint of segment MB. Find the length of the line AK.

Given:
segment AB,
AB = 16 centimeters,
M – midpoint of segment AB,
K is the middle of the MV segment.
Find the length of the segment AK -?
Decision:
Consider the segment AB. Since M is the middle of the segment AB, then AM = MB = 1/2 * 16 = (1 * 16) / 2 = (1 * 8) / 1 = 8/1 = 8 (centimeters).
Since K is the middle of the MV segment, then MK = KV = 1/2 * 8 = (1 * 8) / 2 = (1 * 4) / 1 = 4/1 = 4 (centimeters).
Length of AK wound cut:
AK = AM + MK;
AK = 8 + 4;
AK = 12 centimeters.
Answer: 12 centimeters.
