A triangular pyramid has six edges.
Here's a breakdown to explain why:
A triangular pyramid, also known as a tetrahedron, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.
- Base: The base of a triangular pyramid is a triangle, which has three edges.
- Lateral Faces: The pyramid has three triangular faces that connect the base to a single vertex (the apex). Each of these faces contributes one edge that's already counted in the base, and then one additional edge that rises from the base to the apex. This gives us 3 additional edges.
Therefore, the total number of edges is 3 (base) + 3 (lateral faces) = 6 edges.
