Draw a line segment of length 8.8 cm. Using ruler and compass, divide it into four equal parts. Verify by actual measurement.

Steps:

1. Draw a line segment $\overline{AB}$ of length 8.8 cm.

2. Construct the perpendicular bisector of AB. Let it meet AB at the point M. Then M is the mid-point of AB, so AM = MB = 4.4 cm.

3. Construct the perpendicular bisector of AM. Let it meet AM at the point N. Then N is the mid-point of AM, so AN = NM = 2.2 cm.

4. Construct the perpendicular bisector of MB. Let it meet MB at the point O. Then O is the mid-point of MB, so MO = OB = 2.2 cm.

Thus, the line segment $\overline{AB}$ is divided into four equal parts AN, NM, MO and OB.

On measuring with a ruler, we find AN = NM = MO = OB = 2.2 cm.

Hence, the line segment $\overline{AB}$ has been divided into four equal parts, each of length 2.2 cm.
