Question

If in two triangles ABC and DEF, AB = DE, BC = EF and AC = DF then ∆ ABC ≅ ∆DEF.
Mention the congruence criteria used in this?

Answer 1

the congruence criteria used in this is SSS { side,side,side}

the three sides of A triangle is equal to the coresponding sides of other triangle .so congruence criteria is SSS

Answer 2

Hey mate here is your answer

Criteria used is SSS
