Question
In the given pairs of triangles of the figure, using only RHS congruence criterion, determine which pairs of triangles are congruent. In congruence, write the result in symbolic form:
Solution
In ∆ACE and ∆BDE,
∠ACE = ∠BDE ......(AC || BD, alternate interior angles)
CE = DE ......(Given)
∠AEC = ∠BED ......(Vertically opposite angles)
∴ ∆ACE ≅ ∆BDE ......(ASA criterion)
∴ Triangles are congruent but not by RHS congruence criterion
