In ∆ABC and ∆DEF, it is given that ∠B = ∠E, ∠F = ∠C and AB = 3DE, then the two triangles are (a) congruent but not similar (b) similar but not congruent (c) neither congruent nor similar (d) similar as well as congruent
In ∆ABC and ∆DEF, it is given that ∠B = ∠E, ∠F = ∠C and AB = 3DE, then the two triangles are (a) congruent but not similar (b) similar but not congruent (c) neither congruent nor similar (d) similar as well as congruent

Correct Answer: (b) similar but not congruent

Explanation:

In ∆ABC and ∆DEF,

∠???? = ∠????

∠???? = ∠????

Applying AA similarity theorem,

∆ABC – ∆DEF.

AB = 3DE

AB ≠ DE

∆ABC and ∆DEF are similar but not congruent.
