Recovering the Sequence of Transformations to Show Congruence or Similarity
By James Olsen
Directions: Two figures will be given. Determine if they are congruent or similar. Then state the sequence of transformations that exhibits the congruence or similarity. There is an error in this video!! In example 3, the first translation should be using vector BF (and not vector AF). This is aligned with the following Common Core State Standards for Mathematics: [8.G.2] Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. [8.G.4] Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two- dimensional figures, describe a sequence that exhibits the similarity between them. [G.CO.5] Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. [G.SRT.2] Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar
