Similar Triangles and Other Figures
- Randy Revels
Two figures are said to be congruent if the second can be obtained from the first by a sequence of rotations, reflections, and translations. Previously, we found that we only needed three pieces of information to guarantee that two triangles were congruent: SSS, ASA, or SAS. What about AAA? Are two triangles congruent if all three pairs of corresponding angles are congruent? In this task we will consider what is true about such triangles.
