Question

Which sequence of transformations proves that square ABCD is similar to square A''B''C''D'' ?

A
Square ABCD was rotated 90° clockwise about the origin to create square A'B'C'D' . Then, square A'B'C'D ' was translated one unit to the left and one unit up.

B
Square ABCD was reflected across the x-axis to create square A'B'C'D' . Then, square A'B'C'D' was translated one unit to the left and one unit up.

C
Square ABCD was dilated using a scale factor of 2 and center of dilation at the origin to create square A'B'C'D '. Then, square A'B'C'D' was reflected across the y -axis.

D
Square ABCD was dilated using a scale factor of 2 and center of dilation at the origin to create square A'B'C'D' . Then, square A'B'C'D' was reflected across the x -axis.

Answer 1

b

Explanation:

Answer 2

Answer B

Step-by-step explanation

A is incorrect because depending on the shape, it may or may not have rotational symmetry, so it's safe to go with b. c and d are not correct because dilations do not preserve congruence.
