Question

When rotating the figure you turn it around at a point this can be any coordinate point like the origin which is at?

Answer 1

Yes, if you know the coordinates of a point PP in your original figure as (x,y)(x,y), you can figure out the coordinates of PP following rotation and given by (x′,y′)(x′,y′) as

x′=−yx′=−y

y′=xy′=x
