In the given pairs of triangles of figure, applying only ASA congruence criterion, determine which triangles are congruent. Also, write the congruent triangles in symbolic form.
उत्तर
In ∆PON and ∆MNO,
NO = ON ......(Common)
∠NOP = ∠ONM = 50° + 40 = 90° ......(Given)
∠ONP = ∠NOM = 50° ......(Given)
∴ ∆PON ≅ ∆MNO ......(ASA criterion)
