im.g.1.17.3 Reflecting on Reflection (10)
- mark vasicek
Diego says, "I see why a reflection could take RSTU to R'S'T'U', but I'm not sure where the line of reflection is. I'll just guess." 1. How could Diego see that the reflection could work without knowing where the line of reflection is?
2. How could Diego find an exact line of reflection that would work?
