i really need help with something o.o It's as it follows : A unit square has four corner points with the coordinates below:
A: (7 , 0)
B: (8 , 0)
C: (8 , 1)
D: (7 , 1)

It has been transformed using either

a rotation about the origin through angle u
or
a reflection in a line through the origin at angle u to the x-axis.

Angle u is a multiple of 10 degrees.

The four image points are
A': (-6.578 , 2.394)
B': (-7.518 , 2.736)
C': (-7.176 , 3.676)
D': (-6.236 , 3.334)
