A triangle has three faces, each corresponding to its three sides. These faces are the flat surfaces that make up the triangle, typically referred to as the three edges or sides of the triangle. In a two-dimensional context, the triangle itself is considered a single face, while in a three-dimensional context, a triangular prism has two triangular faces and three rectangular faces.

No.
triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
tetrahedron
The answer is a polyhedron
There are 2 triangle base faces, and 3 rectangle faces. 5 total faces.
four triangle faces.
5 faces

A triangle has 3 sides and 3 vertices. Strictly speaking, the interior of the triangle is not part of the triangle so it has no faces. However, a triangular lamina will have two faces - one from above and one from below.

triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
Five faces and nine edges
tetrahedron
Five faces on a square based pyramid. Never heard of a square based triangle.
A triangle has three faces. In geometry, a face refers to a flat surface of a solid shape. Since a triangle is a two-dimensional shape with three sides, it has three faces. Each side of the triangle forms one of its three faces.
