Decide whether you can use the given information below to prove that △ABC≅△DEF. Explain your reasoning. ∠A≅∠D, ∠C≅∠F, side AC≅ side DF

Decide whether you can use the given information below to prove that △ABC≅△DEF. Explain your reasoning. ∠B≅∠E, ∠C≅∠F, side AC≅ side DE

When a light ray from an object meets a mirror, it is reflected back to your eye. For example, in the diagram, a light ray from point C is reflected at point D and travels back to point A The law of reflection states that the angle of incidence, ∠CDB, is congruent to the angle of reflection, ∠ADB.

a.  Prove that △ABD is congruent to △CBD. Given  ∠CDB≅∠ADB, DB⊥AC Prove  △ABD≅△CBD

b. Prove what classification of triangle is created by ACD.

c. How does changing distance from the mirror affect the ability to see the entire body?
