Tetrahedron
No, a triangle does not have three faces; it is a two-dimensional shape with three sides and three angles. In three-dimensional geometry, the term "face" refers to the flat surfaces of a solid object, such as a tetrahedron, which has four triangular faces. A triangle itself exists only in a plane and does not have any volume or faces like a three-dimensional shape.
A solid with five plane faces is known as a tetrahedron. A tetrahedron has four triangular faces and one additional triangular face, making it a total of five faces. It is one of the simplest three-dimensional shapes in geometry and is classified as a type of polyhedron.
A solid with four faces for maths is a tetrahedron.
Triangle
Four.
By its very nature of being a triangle, and a 2D shape, a triangle cannot have four plane faces. However, a tetrahedron is a polyhedron made up of four triangular faces.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.

Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.

A solid with four faces for maths is a tetrahedron.
The solid figure that has 4 flat surfaces that are triangles is a tetrahedron. A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners. Each of the four faces of a tetrahedron is an equilateral triangle, making it a regular polyhedron.

Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
A four-faced solid is called a tetrahedron.
