Question

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 AA"B"C". Then which of the following is not true?

विकल्प

• ΔΑ'Β'C" ~ ΔΑΒ"C"

• ΔΑ'Β'C" = ΔΑ"B'"C"

• ΔΑΒC = ΔΑ''B"C"

• area ΔABC ≠ area ΔА"В"С"

Answer 1

area ΔABC ≠ area ΔА"В"С"

Explanation:

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.
