A triangle ABC is reflected in y-axis to get triangle A'B'C'. Triangle A'B'C' is reflected in line y = 0, to get △A"B"C". Then which of the following is not true ?
△A'B'C' ~ △A"B"C"
△A'B'C' ≅ △A"B"C"
△ABC ≅ △A"B"C"
△ABC ≠ △A"B"C"

Answer
We know that,
Reflections are isometrics.
∴ Triangles are congruent.
Since, triangles are congruent.
∴ Triangles are similar.
Hence, the statement △ABC ≠ △A"B"C" is not true.
Hence, Option 4 is the correct option.
