Where will we use this?

When we can transform one figure onto another using only rigid transformations, the two figures are congruent. We'll use congruence along with other concepts, like the fact that the interior angle measures of a triangle sum to 180\degree180°180, degree, to find missing measurements.

We'll use this skill in the Find measures using rigid transformations exercise.
