Mr. Williams drew △
A
B
C
on a coordinate grid and asked his students to determine the transformations that will result in a transformed figure
△
A
`
B
`
C
`
such that
△
A
`
B
`
C
`
is similar but NOT congruent to
△
A
B
C
.
Two student responses are shown below.

Student 1: Reflect
△
A
B
C
across the y-axis and then dilate it by a scale factor of 1 with the center of dilation at the origin.

Student 2: Dilate
△
A
B
C
by a scale factor of 2 and the center of dilation at the origin and then reflect it across the x-axis.

Which statement is true?

A.
Neither student 1 nor student 2, because dilations and reflections preserve both side lengths and angle measures.

B.
Both student 1 and student 2, because dilations and reflections preserve angle measures but not side lengths.

C.
Only student 2, because dilations preserve angle measures and side lengths are proportional.

D.
Only student 1, because this dilation preserves angle measures and side lengths.
