Question

how does reflection affect a preimage?
reflection moves a preimage in a circular motion around a point, creating a congruent image.
reflection flips a preimage over a line, creating a congruent image.
reflection slides or shifts from one place to another, creating a congruent image.
reflection changes the size of a preimage without changing the shape, creating a non - congruent image.

Explanation:

• The first option describes rotation (circular motion around a point), not reflection.
• The second option correctly defines reflection: flipping a preimage over a line (like a mirror line) to create a congruent image (same shape and size).
• The third option describes translation (sliding), not reflection.
• The fourth option is incorrect because reflection preserves size and shape, creating a congruent image, not changing size.

Answer:

B. Reflection flips a preimage over a line, creating a congruent image.
