A square pyramid
A pyramid with a triangular base. The faces are 4 equilateral triangles.
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.
