Supporting grades: 8

Description: Sal shows that a given pair of pentagons are congruent by mapping one onto the other using rigid transformations. Created by Sal Khan. So they're congruent if, through some combination of translations, rotations, and reflections, I can make this figure sit right on top of figure C-O-R-A-L. So let's use this tool right over here to do some translations, rotations, and reflections. And let me see if I can get one point in common.
