4. It is called a tetrahedron.
1. triangular prism it has 2 triangular faces. 2.triangular base pyramid, it has 5 triangular faces. 3. square base pyramid, it has 4 triangular faces.
that depends, if it has a square base, it has four faces. but if it has a triangular base, it has three faces.
a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
A triangular base pyramid has 4 faces, 6 edges and 4 vertices
A pyramid will have as many triangular faces as the number of sides its base has, plus one in the shape of its base. This means an octagon based pyramid has nine faces (eight triangular ones plus the octagon base).
Square Pyramid has a square base and 4 triangular sides. Triangular Pyramid has a triangle base and 3 triangular sides.
Including the base it has 4 faces
A pyramid consists of a base and triangular faces that connect the base to a single apex. For a pyramid with ( n ) edges, the number of triangular faces is equal to the number of edges on the base. A pyramid with 10 edges would typically have a triangular base (3 edges), meaning it has 7 edges connecting the apex to the base corners. Therefore, it would have 7 triangular faces.
a pyramid has for faces and a base so all in all 5 faces the four on the outside are triangular and the base is square :)
There are four triangular faces, of which any one can be a base at any instant.
4 the base and 3 sides
There are four faces in a triangular pyramid.
