Help with 3d studio max

[Kääpäkorven Konsuli]

points or corners are known as 'vertices'. A single one is a vertex.
In order to make a valid polygon, you need at least 3 vertices.

Now....if you are looking at making a model for RTW, it needs to ALL be made up of triangles.

Thanks, I always mess vertex and polygon.
So, how do I connect vertices to make a polygon?
