Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Squares ABCD and EFGH share a common center on a coordinate plane, as shown in the figure. is parallel to diagonal .

The number of lines of reflection about which the combined figure can reflect onto itself is .

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

i think the answer is b.

step-by-step explanation:

not 100% sure though.
