The image shows a geometric shape that resembles a tetrahedron (a type of pyramid with a triangular base). Let’s fill in the missing details based on the properties of a tetrahedron.

1. Type: Tetrahedron
2. Faces: 4 (Each face is a triangle)
3. Edges: 6
4. Vertices: 4

These properties belong to a regular tetrahedron, which is the simplest type of 3D shape made from only triangular faces.

Would you like more information or an explanation about tetrahedrons?

Here are 5 related questions to explore:

1. How can the number of edges, vertices, and faces be verified for any polyhedron?
2. What is Euler’s polyhedron formula, and how does it apply here?
3. What are the real-life applications of tetrahedral shapes?
4. How does a tetrahedron differ from other pyramids?
5. Can a tetrahedron be used to tile space without gaps?

Tip: Euler’s formula states that $V - E + F = 2$ for convex polyhedra, where $V$ is vertices, $E$ is edges, and $F$ is faces. Use this to check your results!
