Explanation:
Given:
ΔABC is similar to ΔLMN
To find:
Similarity postulate
Solution:
Two triangles are similar either by two angles or by one angle or two sides or by two angles and one side.
In this question, it is given that two angles are equal
[tex]\begin{gathered} \angle A=\angle L=50^0(given) \\ \angle B=\angle M=75^0(given) \end{gathered}[/tex]
Concept:
AA Similarity Postulate: If two angles in one triangle are congruent to two angles in another triangle, the two triangles are similar. The AA Similarity Postulate is a shortcut for showing that two triangles are similar.
Hence,
The final answer is OPTION A
