Explanation:
I suspect this to be a trick question.
because 2 statements are correct :
B and C.
according to the definition, two triangles are similar if their corresponding angles are congruent (identical) and corresponding sides are proportional (the ratio between the length of corresponding sides is equal for all pairs of corresponding sides, or, in other words, there is one scale factor for all 3 pairs of corresponding sides).
in fact, each criteria alone is sufficient.
if all 3 corresponding angles are identical between both triangles, the corresponding pairs of sides will be proportional.
if all 3 pairs of corresponding sides are proportional, then the corresponding angles are identical.
and the triangles are similar.
