Answer 2

The vertices of any solid are its corners; the places where the edges meet.

A triangular pyramid (tetrahedron) has four vertices, six edges and taking place with the face.

This has been considering in arguing with congruent equilateral triangle by calculating LKM and surface area values.

Based on the vertex, it should be identified with equilateral triangle for operating JLK as base regular tetrahedron.
