Question

how does translation affect a preimage?

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

Explanation:

To determine the correct answer, we analyze each option:

• The first option says translation slides or shifts a preimage, creating a congruent image. This matches the definition of translation (a rigid transformation that moves a figure without changing its shape, size, or orientation, resulting in a congruent image).
• The second option describes a reflection (flipping over a line), not translation.
• The third option describes a rotation (circular motion around a point), not translation.
• The fourth option is incorrect because translation does not change the size of the preimage, and the image is congruent (not non - congruent).

Answer:

A. Translation slides or shifts a preimage from one place to another, creating a congruent image.
