Find the angle at which the circles x\power{2}+y\power{2}+x+y=0 and x\power{2}+y\power{2}+x-y=0 intersect.

If the circles x\power{2}+y\power{2}+2a'x+2b'y+c'=0 and 2x\power{2}+2y\power{2}+2ax+2ay+c=0 intersect 
orthogonally,then prove that aa'+bb'=c+\frac{c'|2}.

Find the angle at which the circles x² + y² + x + y = 0 and x² + y² + x − y = 0 intersect.
If the circles x² + y² + 2a'x + 2b'y + c'
