Define rotations, reflections, and translations using geometric language: angles, circles, perpendicular/parallel lines, and segments.
Match a geometric definition to a transformation type
Problem
Identify the transformation defined by every point moving the same distance and direction.
Big Picture
What this problem is really about
Transformation types are best recognized by their defining invariants, not by how one point happens to move. Translate the phrase “same distance and direction for every point” into one common displacement vector, then contrast that signature with a mirror line, a fixed center and angle, or a center and scale factor.
