a four faced triangle is called a tetrahedron
A four-faced solid is called a tetrahedron.
A triangular pyramid, i.e. a pyramid with only 4 faces and each face a triangle, is called a tetra-hedron. this is because the word tetra-hedron (Greek in origin) has the following meaning: tetra = 4 hedron = faced so a tetrahedron is a four-faced object - the only four faced object is the triangular pyramid.

Pyramid
The point where the altitudes of a triangle meet is called the orthocenter. This point can be located inside the triangle for acute triangles, on the triangle for right triangles, and outside the triangle for obtuse triangles. The orthocenter is one of the four main points of concurrency in a triangle, alongside the centroid, circumcenter, and incenter.
