### Understanding the Regular Tetrahedron

**Figure Description:**
The image depicts a geometric figure known as a regular tetrahedron. A tetrahedron is a type of polyhedron that consists of four triangular faces, with three meeting at each vertex.

**Labels:**
- **b**: This represents the length of the base edge of the tetrahedron.
- **h**: This denotes the height of the tetrahedron, which is the perpendicular distance from the base to the apex (the top vertex opposite the base).

### Detailed Explanation:

1. **Base Edges (b):**
   - All edges of a regular tetrahedron are equal in length. Here, each edge is labeled with \( b \), indicating that the lengths are uniform.

2. **Height of the Tetrahedron (h):**
   - The height \( h \) is the perpendicular distance from a vertex (the apex) of the tetrahedron to the center of the base. 

3. **3D Representation:**
   - Dashed lines are used to depict edges that are not directly visible in a solid three-dimensional view, helping in visualizing the internal structure.

### Educational Insight:
A regular tetrahedron is one of the simplest forms of polyhedra and has significant importance in fields such as chemistry, where it represents the structure of molecules like methane (CH₄). Understanding its properties, such as edge length and height, is fundamental in grasping more complex geometric and spatial concepts.
