Question

Pick the best answer. What is the definition of translation? Responses 1) a type of transformation that doesn't change the size or shape of a geometric figure 2) the transformation of a shape across a line of reflection 3) the circular motion of a figure around a fixed center point 4) a transformation that changes the position of a point or shape

Answer 1

4) a transformation that changes the position of a point or shape

More precisely: a translation moves every point of a figure the same distance in the same direction (i.e., by the same vector), so size and shape stay the same.
