It seems like you're referring to a specific lesson from a curriculum, likely one related to geometry or mathematics, focusing on congruent figures.
While I don't have access to Connexus' specific materials, I can help explain concepts related to congruent figures. Congruent figures are shapes that are identical in form and size, meaning they can be superimposed onto each other without any gaps or overlaps.
If you need help with specific problems or concepts from your quick check, feel free to share those, and I'll do my best to assist you!
