A square based pyramid.
A three-dimensional figure with a polygon base and triangular faces that meet at a common vertex is called a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the apex is the common vertex where all the triangular faces converge. Pyramids are named based on the shape of their base, such as triangular pyramids or square pyramids.
It's a pentagonal pyramid.
It is a square based pyramid
A polyhedron with a polygon base and triangular sides that all meet at a common vertex is known as a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the triangular sides are called lateral faces. The vertex where all the triangular faces converge is referred to as the apex of the pyramid. Each type of pyramid is named based on the shape of its base, such as a triangular pyramid or a square pyramid.
A polyhedron with a polygon base and triangular sides that all meet at a common vertex is called a pyramid. The base can be any polygon (such as a triangle, square, or pentagon), and the triangular faces connect each edge of the base to the apex or common vertex at the top. Pyramids are named based on the shape of their base; for example, a pyramid with a square base is called a square pyramid.

A pyramid.
It sounds like you are describing a square pyramid. A square pyramid has a square base and four triangular faces that converge at a single vertex or apex. This geometric shape is a type of polyhedron known as a pyramid, characterized by its base shape and the triangular faces that connect the base to the apex.
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.
It could be a pyramid shape
The shape you are describing is a square pyramid. It consists of one square base and four triangular faces that meet at a single vertex (the apex). This configuration results in a total of five vertices and eight edges.
