One single complete thought is used in a sher,
When learning and writing a Ghazal Poem.

Last words are the same using the Radif rule,
When learning and writing a Ghazal Poem.

Long, medium or short even meter is a Beher,
When learning and writing a Ghazal Poem.

First sher, both lines end the same is a Matla,  
When learning and writing a Ghazal Poem
