Transformations 3 ways to “move” a figure preimage Image F Rotation about a point

Transformations 3 ways to “move” a figure “maps” Image preimage Reflection in a line

Identify Congruency Two figures are congruent if the second can be obtained from the first by a series of rotations, reflections, and/or translations

Is ABC   A’B’C’ ?

Name the transformation that will map Tree A onto Tree B. Translation

Name the transformation that will map Tree A onto Tree C. Reflection

Name the transformation that will map Tree A onto Tree E. Translation

Name the transformation that will map Tree A onto Tree D. Rotation or Translated and Reflected

Watch Out There may be more than one combination of transformations that maps one figure onto another. 2 reflections over intersecting lines is the same as a rotation
