Intro to Triangular Similarity

What is the ratio of any two corresponding sides?  $$\frac{new}{old}$$  

The Angle-Angle Similarity (AA ~) Theorem states if two angles of one triangle are _______________ to two angles of another triangle, then the triangles are ____________________.

The Side-Side-Side Similarity (SSS ~) Theorem states if the corresponding sides of two triangles are _____________________, then the triangles are _________________.

The Side-Angle-Side Similarity (SAS ~) Theorem states that if two sides of one triangle are ________________ to two sides of another triangle and their _________________ angles are congruent, then the triangles are similar.

What is triangular similarity

Give the reason for similarity

Do you think these triangles are similar? 

Determine if the triangles are similar. If they are, identify the triangle similarity theorem(s) that prove(s) the similarity.

Which triangle is not similar to any of the others?
