Congruent Transformations




 

Videos and lessons to help Grade 8 students 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.

Common Core: 8.G.2

Suggested Learning Targets


  • I can define congruency
  • I can identify symbols for congruency
  • I can apply the concept of congruency to write congruent statements.
  • I can reason that a 2-D figure is congruent to another if the second can be obtained by a sequence of rotation, reflections, and translation.
  • I can describe the sequence of rotations, reflections, translations that exhibits the congruence between 2-D figures using words.

The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of the CCSS. Each video is an audiovisual resource that focuses on one or more specific standards and usually includes examples/illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard although the examples can be adapted for instructional use.
