question
what is the word that describes a transformation that produces a congruent image, preserving size?
answer attempt 1 out of 1
options: transformation, dilation, rigid motion or isometry, slope

Explanation:

A rigid motion (isometry) is a transformation that preserves distance and angle, producing a congruent image (same shape and size). Transformation is a general term, dilation changes size, and slope relates to lines, not congruence preservation.

Answer:

Rigid motion or Isometry
