• Two triangles are similar if they have: all their angles equal.

• Corresponding sides are in the same ratio.

Answer 2

Answer:

There are three criteria for proving that triangles are similar: AA: If two triangles have two pairs of congruent angles, then the triangles are similar. SAS: If two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar.
