Check for page ID & query posts for particular category

Hi,
I am just about learning, so please excuse me if i am asking the obvious.

I have 2 pages
Page 1 = Poetry, page_id = 101
Page 2 = Humor, page_id = 102

Both pages have a static piece of text, below which i would like to show a list of post_titles, that belong to the parent category ‘poetry’ & ‘humor’

My template seems to have a page.php.
Here i would like to check which page is being viewed

if(page_id=101)
<?php query_posts(‘category_name=poetry’); ?>

if(page_id=102)
<?php query_posts(‘category_name=poetry’); ?>

I am not sure how to put in the code for pageID.
Any help is great help
Thanks in advance
Regards
Deepa
