Question

In ∆DEF , angle E =angle F .Which of it's two sides are equal​

Answer 1

Answer:

In △ABC and △DEF,

∠A=∠E=40  

∘

 

ED

AB

​  

=  

EF

AC

​  

 

Thus, △ABC∼△DEF (SAS rule)

or ∠C=∠F=65  

∘

 

Now, In △ABC,

∠A+∠B+∠C=180 (Sum of angles of triangle)

40+65+∠B=180

∠B=180−105

∠B=75

therefore .... DE=EF
