Yes... considering the top view the Lowe's stern looks like an horizontal T ...sort of |--
but other baidarka's sterns (e.g. nikumi) got sort of triangolar plate over that T... so the top view looks like a triangle. (mmmh... not sure I told it clear enough)
that's what i call "triangular plate" http://tinyurl.com/68ceowg

Actually once the sterns are skinned and as far as the triangular plate is over the waterline... they just work the same. Maybe the triangular plate provides a bit more volume than the traditional lowe's T stern in case it goes under the waterline.

Here is a T stern very low in the water (Brinck's baidarka) http://tinyurl.com/4vj57qk
And here is a triagular stern http://tinyurl.com/67q45ze

A couple of T sterns more:
