Both triangles BAC and TRS are similar triangles by SAS Similarity. (Option C)
Recall:
- Based on the SAS Similarity Theorem, two triangles are similar if they have two pairs of proportional side lengths and a pair of included angle measure that are congruent.
In the diagram given:
Both triangles have two proportional sides - 15/2 = 21/7 = 3
They also have a pair of included angles (42 degrees).
Therefore, both triangles BAC and TRS are similar triangles by SAS Similarity. (Option C)
