Question

In the adjacent figure Δ ABC ≅ Δ DEF then find E ?​

Answer 1

Answer:

∠E = 40°

Step-by-step explanation:

Δ ABC ≅ Δ DEF               [By ASA Congruency]

⇒ ∠A = ∠D = 60°              [Corresponding Parts of Congruent Triangles]

⇒ ∠C = ∠F = 80°               [Corresponding Parts of Congruent Triangles]

Using angle sum property in Δ DEF,

∠D + ∠E + ∠F = 180°

60° + ∠E + 80° = 180°

∴ ∠E = 40°

Hope that helped!
