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 is formed by a polygonal base and triangular faces that connect the base to a single apex. The number of triangular faces in a pyramid is equal to the number of sides on the base polygon. For example, a pyramid with a square base has four triangular faces, while a pyramid with a triangular base has three triangular faces. Thus, the total number of triangles in a pyramid varies depending on the shape of the base.
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 triangular base pyramid, also known as a tetrahedron, has a triangular base and three triangular lateral faces. In this shape, there are no pairs of parallel faces, as each face is inclined at different angles relative to the others. Therefore, the number of pairs of parallel faces on a triangular base pyramid is zero.
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.
