Question
In the given figure, which pairs of triangles are congruent by SAS congruence criterion (condition)? if congruent, write the congruence of the two triangles in symbolic form.
Solution
In ∆LMN and ∆OMN,
MN = MN .....(Common)
LM = OM ......(Given)
∠LMN = ∠OMN = 40° ......(Given)
∴ ∆LMN ≅ ∆OMN ......(SAS criterion)
