Math Problem Statement
State if the two triangles are similar and justify the choice using similarity criteria.
Solution
The question asks if the two triangles are similar and provides four choices with different similarity criteria. Let’s analyze:
Observations:
- Given triangles: (bottom triangle) and (top triangle).
- Labeled angles:
- Both triangles have a pair of marked congruent angles ( and ).
- The shared bottom angle, labeled as in and in , is congruent because of the same marking.
Solution:
The AA (Angle-Angle) Similarity Criterion states that two triangles are similar if two angles in one triangle are congruent to two angles in another triangle. In this case:
- (given),
- (given).
Thus, by AA Similarity, .
Correct Answer:
B) Yes; by AA Similarity.
