Math Problem Statement
Solution
In the image, four pairs of similar triangles are shown. To determine the correct similarity statement for the fourth pair of triangles (Triangle and Triangle ):
Step-by-Step Analysis:
-
Angle Matching:
-
For triangle :
- (because the sum of angles in a triangle is )
-
For triangle :
- (similarly from triangle angle sum property)
-
-
Corresponding Angles: Since the angles are the same, the triangles are similar by the AA (Angle-Angle) Similarity criterion. Now, we need to match the corresponding vertices:
- corresponds to (both are ),
- corresponds to (both are ),
- corresponds to (both are ).
Conclusion:
The correct similarity statement is Triangle , since the vertices match based on corresponding angles.
