Question
Identify the similarity criteria if the two triangles in the figure are similar
- SAS similarity criteria
- SSS similarity criteria
- AA similarity criteria
- Data inadequate
Hint:
The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar
The correct answer is: SAS similarity criteria
ECD= ACB
Here, two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar by SAS similarity criteria.
By SAS similarity criteria, the given two triangles are similar.
