What are some similarities between square dance and line dance?

So a couple of differences one, the music, so line dance music is done to commercially played country music on the radio. ... And square dancing is a called dance where the caller tells you what to do. And there is the difference between line dancing and square dancing

Square dancing is very old. It is almost exclusively done to a fiddle song. It is ALWAYS done with couples. It requires a "caller," someone who calls the parts of the dance.

Line dancing is newer, is done to either a live band or pre-recorded music, does not require a fiddle, does not require partners, and has no caller.

No question so i cant answer
