what are the most recognized constellations located towards the southwest sky???
Southwest sky? You do realize that the sky rotates every 24 hours, right?
Also, not everyone sees the same exact sky - for someone in Australia, the sky looks a lot different to the southwest right now than it does for someone in Maine.
To top it off, if you look southwest every day at the same time and same location, you'll see different constellations as the Earth orbits the Sun.
Separate names with a comma.
