A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
A tetrahedron is a triangular based pyramid that has 6 edges, 4 faces and 4 vertices
A pyramid does not need to have any equal sides. A REGULAR pyramid has as many equal sides as the number of sides on the base. So, a triangular pyramid (tetrahedron) will have 3 equal faces, a square based pyramid will have 4, etc.
Your roof is a square based pyramid.
None because a tetrahedron is a triangular based pyramid which has 4 faces, 6 edges and 4 vertices.
A square based pyramid has 5 faces whereas a triangular based pyramid which is a tetrahedron has 4 faces.
A triangular-based pyramid is called a Tetrahedron. :)
A tetragonal is square shaped whereas a tetrahedron is a triangular based pyramid.
If you mean a tetragon then it is a square whereas a tetrahedron is a triangular based pyramid
A TRIANGLE based PYRAMID is called a tetrahedron.
A square based pyramid is called a square pyramid
A triangular pyramid is called a Tetrahedron ■
Maybe a Square based pyramid? * * * * * No. A triangle based pyramid (tetrahedron).
It is a tetrahedron that is a triangular based pyramid
A triangular pyramid is a 3-dimensional geometric figure that has 5 sides. Four triangle shaped sides that are connected to one square shaped based. * * * * * If it has a square shaped base then it is a square based pyramid! A triangular pyramid has 4 faces. It is also called a tetrahedron.
A rectangle based pyramid!
