I was told it is in the Euphorbia family. What is the pictured succulent and how should I plant it?

This is a Euphorbia trigona.
This plant needs a sunny and dry location. When in doubt if it needs water--don't water it.
You can propagate from cuttings. Use a clean knife to make the cut, and wash the sap (which is a skin irritant) under running cold water.
Allow the cutting to dry on a paper toweling for a few days, then plant in a well draining cactus mix.
Don't use to large of a pot and do not water for the first week.
