A geometry student named Mary claims that the two triangles in the diagram below are not similar to one another. She asserts that the ΔABC is not similar to ΔXYZ because triangle XYZ is bigger. Explain why Mary is mistaken in her conclusions about ΔABC and ΔXYZ. In writing your response, be sure to explain the difference between similarity and congruence. Also be sure to include important math concepts such as similarity, proportionality, and corresponding sides.
