## Essential Understanding

Two figures are

**congruent**if and only if there is a sequence of one or more rigid motions that maps one figure onto the other. So what does that mean??? If you can perform a composition of transformations AND the shapes lay on top of each other AND are exactly the same, then they are congruent. If you perform a composition of transformations AND the shapes don't lay perfectly on top of each other, then the shapes aren't congruent. That's it! For the two problems below, perform a composition of transformations. Take a screen shot of your work and insert it into the appropriate google slide. Are the shapes congruent?
