Please help identify this symbol

Good morning, 

 

This symbol attached recently started appearing on all of my drawings and my default for dimensioning, placing objects, etc is no longer orthogonal. It's like "control" is always being pressed, even though I'm not. I know I must've hit something to turn it off and I'm pretty sure that's what this symbol means. Can anyone tell me how restore it?

It's Angle Snaps

The icon is letting you know your angle snap are turned off.

Great. How do I turn it back on?
