Answer:

Step-by-step explanation:
Given:
In ΔLMN and ΔXYZ, 
To find: criteria that needs to be shown to prove ΔLMN
ΔXYZ using SAS similarity theorem
Solution:
According to SAS Similarity Theorem, if two sides in one triangle are proportional to two sides in another triangle and the included angle between the sides are congruent, then the two triangles are said to be similar.
In ΔLMN and ΔXYZ,

So, ΔLMN
ΔXYZ by SAS similarity theorem if
