The vertices of AABC are A(-4,5), B(-2,2), and C(-5,2). If AABC is reflected across the line y = 1 to produce the image AA'B'C', find the coordinates of the vertex A
The coordinates of A' after a reflection across the line y = 1 are
(Type an ordered pair)

helppp!! Pls thanks

Okay, so the square all sides are 7 so the diagonal using the 45-45-90 triangle theorem you can find that the diagonal is 7 times the square root of 2.  The diagonal of the rectangle can be found because it will divide the rectangle into 2 30-60-90 triangles.  The hypotenuse is 2 times the smallest side in a 30-60-90.  We know that the smallest side is 7.  So the hypotenuse is 14 (I think there is an error in the question).  We know this using the 30°-60°-90° Triangle Theorem.  Because 14 is not 2 times 7 times the square root of 2.  Anna is incorrect.  I think.
