🔍 Understanding the Task

We are given a set of geometric shapes, and we need to classify them into two categories:
- Plane Figures: 2D shapes (flat, have length and width)
- Solid Figures: 3D shapes (have length, width, and height)

Below is the list of shapes shown in the image:

1. Hexagon
2. Triangle
3. Rectangle
4. Pentagon
5. Square
6. Cone
7. Triangular Pyramid
8. Rectangular Pyramid
9. Pentagonal Prism
10. Cube
11. Truncated Pyramid
12. Parallelogram

✔ Step-by-Step Classification

#### 🟦 Plane Figures (2D)
These are flat shapes with only two dimensions (length and width). They lie on a plane.

- Hexagon → 2D shape
- Triangle → 2D shape
- Rectangle → 2D shape
- Pentagon → 2D shape
- Square → 2D shape
- Parallelogram → 2D shape

✔ So, Plane Figures:
> Hexagon, Triangle, Rectangle, Pentagon, Square, Parallelogram

#### 🟨 Solid Figures (3D)
These are three-dimensional shapes that occupy space.

- Cone → 3D (has a base and height)
- Triangular Pyramid → 3D (also called tetrahedron)
- Rectangular Pyramid → 3D
- Pentagonal Prism → 3D (two pentagons connected by rectangles)
- Cube → 3D (a special type of prism)
- Truncated Pyramid → 3D (a pyramid with the top cut off)

✔ So, Solid Figures:
> Cone, Triangular Pyramid, Rectangular Pyramid, Pentagonal Prism, Cube, Truncated Pyramid

✔ Final Answer

| Plane Figures | Solid Figures |
|-------------------------------|--------------------------------------|
| Hexagon | Cone |
| Triangle | Triangular Pyramid |
| Rectangle | Rectangular Pyramid |
| Pentagon | Pentagonal Prism |
| Square | Cube |
| Parallelogram | Truncated Pyramid |

💡 Explanation

- Plane figures are flat and can be drawn on paper.
- Solid figures have depth and volume — they take up space.
- The key difference is dimensionality: 2D vs. 3D.

This sorting helps students understand the basic distinction between flat shapes and real-world objects.
