![### Geometry of a Tetrahedron
**2. Given the following tetrahedron, name the following:**
a. **Vertices**
b. **Edges**
c. **Faces**
d. **Intersection of the face DRW and edge RA**
e. **Intersection of face DRW and face DAW**
### Diagram Explanation
The diagram on the right illustrates a tetrahedron with vertices labeled as D, R, W, and A. The solid lines represent the edges connecting these vertices to form triangular faces. A dashed line between R and A indicates an edge not directly visible on the current plane of view.
- **Vertices**: Points D, R, W, A
- **Edges**: Lines (e.g., DW, WR, RA)
- **Faces**: Triangular areas (e.g., DRW, DAW)
### Specific Intersections
- **Intersection of the face DRW and edge RA**: This point would be where the defined face and edge meet, which is not specified in the image but involves considering the geometry and potential hidden lines.
- **Intersection of face DRW and face DAW**: The line DA is the intersection line common to both triangular faces DRW and DAW.
This exploration of the tetrahedron involves identifying the fundamental triangular shapes and interaction points.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F79d4d229-649f-4192-a00b-385a235528b8%2Fda9d7a71-9f25-4722-a458-159bafbf90b7%2Fn5uhrk_processed.jpeg&w=3840&q=75)
