Question

Rock designed a logo by transforming ABCD to get A'B'C'D' as shown below. Identify the transformation performed by Rock.

• A. Reflection over the line $x=0$
• B. Translation of 1 unit toward the right
• C. Reflection over the line $y=0$
• D. Rotation of ${90}^{\circ }$ about the origin in the clockwise direction

Answer 1

The correct option is A Reflection over the line $x=0$

We can say that the image A'B'C'D' has been obtained by reflecting the preimage ABCD over the y-axis.
We know that reflection involves flipping an object over a straight line or axis of reflection to get the reflected image. Here, the logo has been reflected along the y-axis, which is the same as the line $x=0$.
Hence option a is the correct answer.
