FLASHCARD QUESTION
Front
What are the criteria for triangle similarity?
Back
The criteria for triangle similarity are: 1. AA (Angle-Angle) Criterion: If two angles of one triangle are equal to two angles of another triangle, the triangles are similar. 2. SSS (Side-Side-Side) Criterion: If the sides of one triangle are proportional to the sides of another triangle, the triangles are similar. 3. SAS (Side-Angle-Side) Criterion: If two sides of one triangle are proportional to two sides of another triangle and the included angle is equal, the triangles are similar.
