Final answer:
To determine if triangles are similar, compare their corresponding angles and side lengths. The similarity statement is written using the similarity symbol '~' followed by the triangle names. The scale factor is the ratio of corresponding side lengths.
Step-by-step explanation:
The provided information is not clear enough to determine if the triangles are similar. However, we can discuss how to determine if triangles are similar. Two triangles are similar if their corresponding angles are congruent and their corresponding side lengths are proportional.
The similarity statement would be written as 'ΔBAO ~ ΔB₁A₁O', using the similarity symbol '~' to denote similarity.
The similarity theorem would be 'The Side-Side-Side (SSS) Similarity Theorem' if the corresponding side lengths are proportional. The scale factor is the ratio of corresponding side lengths, so it would be 'AB/A₁B₁' to find the scale factor of Triangle A to Triangle B.
