It sounds like you're looking for the slant height.
The height of the triangular face of a pyramid is called the slant height.
The solid shape that has one square face and four triangular faces is called a pyramid. If you were to have a shape that had four triangular faces and no square face, it would be called a triangular pyramid.
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
a triangular pyramid is a triangular prism but it doesn't work vise-versa. The prism needs a minimum of 1 triangle face but it can have more.A pyramid can only have one triangular face.
there is four faces on a pyramid
Triangular Prism, Triangular Pyramid.
A pyramid has triangular faces that converge at a single point called the apex. The base of the pyramid can be any polygon, and the number of triangular faces corresponds to the number of sides on the base. For example, a square pyramid has four triangular faces and a square base.
If the base of the pyramid is a triangle then all its faces would be triangular in shape.
A triangular based pyramid with 4 equilateral triangle faces is a tetrahedron
A triangular pyramid is a pyramid that has 4 faces where each face is a triangle. Just type it in on www.google.com/images
A triangle if it is a triangular based pyramid
it has 3 edges a triangle has 1 face a trianguler pyramid has 4 faces a triangular pyramid has 5 faces
