I'm a shape, basically.
I might be a cute.
If one side of me gets over 90 degrees,
I don't get hot.
I get obtuse.
I might be right.
If I'm right, one side of me is always the hy(pot en use) side.
I may be S.CA l! E.NE.
Or, I may be I so..c E.L? E S!
There's more than one side to me.
There's more than two sides to me.
There isn't four sides of me. Too square..
I was the site of a terrible fire in NYC in 1911.
Many died, but it led to increased safety measures that would save lives.
I may get in between two in love, causing a problem.
Even though I don't know all the angles, I'm willing to tri.
What am I?
