In the ∆ABC and ∆DEF, B = E, F = C and AB = 3DE. Then, the two triangles are


In ∆ABC and ∆DEF,

B = E,


F = C and AB = 3DE



We know that,


If in two triangles corresponding two angles are same, then they are similar by AA similarity criteria.


Also, we know that two triangles are congruent if they have the same shape & size and satisfy the rule of congruency but ∆ABC and ∆DEF do not satisfy any rule of congruency, which are SAS, ASA, AAA and SSS, so both are not congruent.
