Question

Your friend wanted to adjust the position of the birthday banner from ABC to A'B'C'. Help him identify the transformation required to set the banner.

• A. Translation
  
• B. Reflection
  
• C. Rotation
  
• D. None of these
  

Answer 1

The correct option is B Reflection


The transformation required to adjust the birthday banner from ABC to A'B'C' is reflection, as reflection involves flipping an object over a straight line or axis of reflection to get the reflected image. In reflection, the original figure and its image are identical.

In the figure shown above, the preimage ABC is reflected or flipped along the $x$-axis to form A'B'C'. So, A'B'C' is a reflection of ABC.
