How do you divide a hexagon into 9 congruent parts?

I couldn't. Here is a way to divide it into eight equal parts.

okay, thanks anyway.

To divide a hexagon into 9 congruent parts, you can follow these steps:

1. Draw a hexagon: Start by drawing a hexagon using a ruler and a pencil. A hexagon is a six-sided polygon with all sides of equal length.

2. Draw a line segment: Draw a line segment connecting any two opposite corners of the hexagon. This line will divide the hexagon into two congruent trapezoids.

3. Bisect each trapezoid: Find the midpoint of the line segment you drew in step 2. This can be done by measuring the length of the line and dividing it by 2. From the midpoint, draw a line perpendicular to the base of each trapezoid. These lines will divide each trapezoid into two congruent triangles and a smaller trapezoid.

4. Divide the smaller trapezoids: To further divide the smaller trapezoids into congruent parts, draw lines parallel to the bases of each trapezoid. These lines should connect the corresponding vertices on opposite bases of the trapezoids. This will divide each smaller trapezoid into three congruent triangles.

5. Repeat for other trapezoids: Repeat steps 3 and 4 for the other trapezoid formed in step 2. Following these steps will divide the hexagon into 9 congruent parts.

Remember to use a ruler and be precise in your measurements and drawings to achieve accurate results.
