Do you mean you want to subdivide the mesh?

As @cherno says, you have to reset the vertices and triangles arrays. Depending on what you are doing, you could simplify things by hacking a bit. That is you collapse the large triangle by giving it three of the same vertices, then add the new vertex and two triangles to the end of the two arrays.

You can't just split a triangle into two. You would need to re-do the whole mesh becasue you have to add a new vertex.
