Exploring Similar Polygons and AA Similarity

What are the two main criteria for polygons to be considered similar?

• All sides are proportional and all angles are proportional.

• All angles are equal and all sides are equal.

• Corresponding angles are proportional and corresponding side lengths are congruent.

What does the Angle-Angle (AA) similarity criterion state?

• If one angle of one triangle is congruent to one angle of another triangle, then the triangles are similar.

• If two sides of one triangle are proportional to two sides of another triangle, then the triangles are similar.

• If all three angles of one triangle are congruent to all three angles of another triangle, then the triangles are similar.

• If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
