Question

If you wish to show that two triangles are similar, which statement(s) is correct? You may choose more than one correct answer.

It is enough to show that all three pairs of corresponding sides are in the same ratio.
It is not enough to have information about only sides or only angles.
It is enough to show that two pairs of corresponding angles are congruent.
It is enough to show that two pairs of corresponding sides are in the same ratio.
It is enough to show that one pair of corresponding angles is congruent.

Answer 1

It is enough to show that all three pairs of corresponding sides are in the same ratio.

It is enough to show that two pairs of corresponding angles are congruent.

Explanation:

If you know that the corresponding sides have the same ratio, then both triangles will be similar (SSS Similarity)

If 2 corresponding angles are congruent, you know the 3rd one is too (Triangle Angle Sum) which makes the triangles similar (AA Similarity)
