Question 499182
answer is (3)
3 angles are congruent proves that the triangles are similar.
they are not necessarily congruent.
their corresponding sides are in proportion to a common ratio.
only if the common ratio is 1:1 will they be congruent.

example:
triangle 1 and triangle 2 have equal angles all around.
their corresponding sides are in the common ratio 1:2
this means that the lengths of the sides of triangle 2 are 2 times the lengths of the corresponding sides of triangle 1.
the triangle are similar.
their angles are equal and their sides are in proportion.
if the common ratio was 1:1 then the sides would be congruent and the triangles would be congruent.
