# Joining two sentences using “which”?

I have following constructions,

1. The geometric reconstruction of the pentagon models is then performed using graph cut approach.
2. The geometric reconstruction of the pentagon models can be considered as a corner fixing dilemma.

If I make a one sentence using which; then am I placing which at the correct place obeying the correct English grammar (see in my below sentence please)?

The geometric reconstruction of the pentagon models is then performed using a graph cut approach which can be considered as a corner fixing dilemma.

• Hi gnp, this seems to be a proofreading question, which we don't generally tend to support here on ELL. Can you add more information to your question, such as what parts of the sentence you think might not be correct and why? – WendiKidd Mar 24 '13 at 20:31
• @WendiKidd: sorry, i will update the post – gnp Mar 24 '13 at 20:39
• gnp, how about "The geometric reconstruction of the pentagon models, which can be considered as a corner fixing dilemma, is then performed using graph cut approach"? – user114 Mar 24 '13 at 20:55
• @Carlo_R.: that mean, the description on first thing always come after that? like The geometric reconstruction of the pentagon models, which can be considered as a corner fixing dilemma, is...... – gnp Mar 24 '13 at 21:06
• gnp, sorry I'm a learner who is learning English via osmotic process, not via English grammar. However I suppose that both a RC and a NRC should follow the NC. I hope compentent grammarians answer to your question giving all the details. – user114 Mar 24 '13 at 21:15

The geometric reconstruction of the pentagon models is then performed using a graph cut approach which can be considered as a corner fixing dilemma.

In that sentence, which is referring to "a graph cut approach."

If you want to use which referring it to "the geometric reconstruction" you should use a sentence similar to the following one:

The geometric reconstruction of the pentagon models, which can be considered as a corner fixing dilemma, is then performed using a graph cut approach.

I would rather use the following sentence, but that is probably a matter of style.

The geometric reconstruction of the pentagon models is then performed using a graph cut approach, and it can be considered as a corner fixing dilemma.

• this mean, "it" refers to the geometric reconstruction or..? – gnp Mar 24 '13 at 22:39
• It refers to "the geometric reconstruction." – kiamlaluno Mar 24 '13 at 22:45
