All but one face must be triangular. The base can be any polygon, including a triangle.
triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
Rectangular pyramids and triangular pyramids both have triangular faces.
Because if their lateral faces were not triangular they would not be called pyramids!
Triangular pyramids have 4 faces(3 and a base) Traditional pyramids have 5 faces( 4 and a base)
Four face.
Pyramids.
The 7-letter word for a 3D shape with triangular faces is "pyramid." A pyramid is a polyhedron with a polygonal base and triangular faces that meet at a common vertex called the apex. Pyramids are classified based on the shape of their base, such as square pyramids, triangular pyramids, pentagonal pyramids, etc.
they are both types of pyramidsThey're both triangular pyramids, and all of them have a base, multiple faces, and at one end the faces come to a point.* * * * *They are NOT both triangular pyramids!
Pyramids have some triangular faces.
A triangular prism has 5 faces. Pentagonal prisms and hexagonal pyramids have 7.
A triangular prism has two triangular bases and three lateral rectangular faces. It has five faces in all so that it is a pentahedron.A triangular pyramid has a triangular base and three triangular lateral faces. It has 4 faces in all so that it is a tetrahedron.
Square pyramids have a square base and four triangular faces, while triangular pyramids have a triangular base and three triangular faces. The number of sides and the shape of the base are the main distinguishing factors between the two types of pyramids. Additionally, the angles and dimensions of the faces will vary based on the shape of the base in each type of pyramid.
