**8. Isosceles Trapezoid with Two Parallelogram Cavities**

The diagram illustrates an isosceles trapezoid featuring two parallelogram-shaped cavities. The trapezoid is highlighted in blue, and specific measurements are marked along its edges. 

**Trapezoid Measurements:**

- Horizontal segments (top edge): 1 inch, 2 inches, 4 inches, 4 inches, 2 inches, 1 inch.
- Vertical segments (left side): 2 inches from the top, 3½ inches in the middle, and 2 inches at the bottom.
- Horizontal segments (bottom edge): 2 inches, 4 inches, 3 inches, 4 inches, 2 inches.

**Cavities:**

- The parallelogram cavities are positioned symmetrically within the trapezoid.
- The dotted lines labeled 'x' and 'y' indicate axes of symmetry. The 'x' axis is horizontal, while the 'y' axis is vertical, intersecting at the center of the trapezoid.

This educational diagram serves to demonstrate the structure and symmetry of an isosceles trapezoid with internal features, useful in geometrical studies.
