Answer 1

what do you think

Answer 2

Yes.

Answer 3

good :) thats right if two triangles are congruent, they must be similar also, cuz by definition of congruent triangles, all corresponding parts are equal between both the triangles - making the ratio of all corresponding sides to be equal to 1. Since for similar triangles we just need the ratio of all corresponding sides to be equal, two congruent triangles always satisfy this requirement - thus two congruent triangles are always similar also.
