Gordon and tess are trying to determine whether δabc and δfge can be proven congruent through rigid motions. gordon says that δabc ≅ δfge because δabc can be reflected over the line x = 1 to create δfge. tess says δabc ≅ δfge because δabc can be translated by the rule (x + 5, y − 7) to create δfge.

who is correct?

gordon only
tess only
both gordon and tess
neither gordon nor tess
