Question

Which of the following statement is correct regarding the reflection of rectangle ABCD to form rectangle A'B'C'D'?

• A. On reflection along the x-axis, length of A'B' is decreased
• B. On reflection along the x-axis, length of C'D' is increased
• C. On reflection along x-axis, length of AD becomes equal to length of A'D'
• D. Size of ABCD and A'B'C'D' are different upon reflection on x-axis

Answer 1

The correct option is C On reflection along x-axis, length of AD becomes equal to length of A'D'



ABCD is getting reflected along x-axis to form A'B'C'D'.

If a rectangle is reflected along the x-axis, the coordinates will change, but its length remains constant.

So, upon comparing the lengths, we see:
AB = A'B'
BC = B'C'
CD = C'D'
AD = A'D'

So, the correct option is option 'c'.
