The rotation matrix for a 90° rotation is [[0,-1],[1,0]]
More simply, if our shape is a function of x and y, we swap x and y and then negate y.
For instance: if our function is y=x, then the 90° rotation would be x=-y

What is an acute angle of a shape?
An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
