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)
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.
Four face.
Pyramids.
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 that do not have parallel faces are known as irregular or non-regular pyramids. Unlike regular pyramids, where the base is a regular polygon and the triangular faces are congruent, irregular pyramids can have bases of varying shapes and sizes, leading to non-parallel faces. An example of this is a pyramid with a base that is a scalene triangle, where the triangular faces can differ in size and shape.
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.
