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 ∆DOF and ∆HOC,
DO = HO ......(Given)
FO = CO .....(Given)
∠DOF = ∠HOC ......(Vertically opposite angles)
∴ ∆DOF ≅ ∆HOC ......(SAS criterion)
