A tetrahedron has four vertexes and four faces and six edges.
Triangular Pyramid
It can be a pyramid shape with an equilateral triangle base
That could be a triangular pyramid.
equilateral triangle
The tetrahedron has 4 equilateral triangles as its faces.
Yield signs are triangular, but have rounded corners. An actual triangular shape, if equilateral, would be a regular polygon.

equilateral triangle
A triangular based pyramid.
The tetrahedron has 4 equilateral triangles as its faces.
A solid shape made out of eight equilateral triangles is called a triangular bipyramid. This polyhedron consists of two triangular pyramids (tetrahedra) joined at their bases, creating a three-dimensional figure with eight triangular faces, six edges, and four vertices. The symmetry and uniformity of the equilateral triangles give it a distinct geometric shape.
The shape with four triangular faces that are all equilateral is a tetrahedron. A tetrahedron is a type of polyhedron that has four vertices, six edges, and four triangular faces. Each face is an equilateral triangle, making it one of the simplest three-dimensional shapes.
