How to split/slice a polygon without subdivide?

Question

So I'm relatively new to Blender AND human modelling and was working on this low poly CG character. This torso was built from a cylinder primitive and now I want to split/slice at the very bottom face in two (then I can cut half of it and mirror, extrude the leg or whatever).

The face can't be subdivided and I just want to slice the face in two along the line (shown in the picture as a cyan line) connecting the center vertices.

Cyan line is the slicing guide

This is Blender 2.66. What do I do to accomplish this?

You could use the knife tool. Press K and then click where you want to make cuts. Press ⏎ Enter or Space to confirm:

Or you could use the join tool. Select the vertices you want to connect with an edge and press J:

Ah thanks! Knife tool was what I needed! And the illustrations helped too! – Samik Sengupta Aug 13 '14 at 18:22

What is the difference between using J and pressing F to join vertices? – Neil Aug 14 '14 at 08:21

@Neil J cuts the face(s) between the selected vertices with an edge, F just creates an edge. In the above example, J results in two faces where there used to be one. F would not cut the face, resulting in the same number of faces (but with a floating edge between to verts). – gandalf3 Aug 14 '14 at 22:08
'space bar' to execute cutting! – Jinbom Heo Jul 20 '15 at 15:13

Thanks a bunch for the J shortcut - very useful! – Martin Häusler Dec 26 '19 at 20:00

Select both vertices and connect them.

Mesh -> Vertices -> Connect (menu)
JKey (shortcut)

While the knife can be used for this purpose too, for quick cuts this is faster.

This also works...

Between many selected vertex pairs (you can connect multiple faces at once).
Between 2 vertices - to connect vertices across multiple faces.

The easiest option is to use the Vertex Connect tool.

To do so:

Select the two vertices.
Press the J key or search for the "Vertex Connect" tool.
