Parallelogram JKLM has vertices J(2,1), K(7,1), L(6,-3), and M(1,-3). What is the coordinates of the image of K if the parallelogram is rotated 270 degrees about the origin? a
K'(1,7)
b
K'(1,-7)
c
K'(-7,1)
d
K'(7,-1)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
