  New Massive Gravity is an alternative theory to General Relativity that is
used to describe the gravitational field in a (2+1)-dimensional spacetime.
Black hole solutions have been found in this theory, in particular an
asymptotically anti-de Sitter rotating black hole. We analyse some features of
this solution as its event horizon, black hole area and distance to the
horizon, specially in the rotating extreme case, showing that they have shared
features with extreme black holes in 4-dimensional General relativity. This
limit case is interesting in the search of geometric inequalities as the ones
found for the Kerr black hole in (3+1)-General Relativity.
