Why would it sprout decimals?  It's on a lattice point.

A(1,-1) -- Quadrant IV
Reflect across y-axis
A'(-1,-1) -- Quadrant III
Rotate 180º
A" ()-- Which Quadrant?  Gives it away.

2? @tkhunny (im a moron sorry)

tkhunny · Answer

Quadrant III to Quadrant II results from a 90º rotation.  You'll have to go more than that.  It still won't sprout decimals.

@tkhunny so 90 more would move it to 1? (i was thinking 180 would just bring it back on itself but then I remembered that would be 360 so instead its half of that and only really flipping right?)
