Question

In ∆ DEF,DE=DF and <E=40°, then find the measure of <F ?​

Answer 1

Answer:

I am not able to understand question

Answer 2

Answer:

I hope I have solved your problem

Step-by-step explanation:

In triangle DEF

DE=DF

=> angle(E) = angle(F)

(Angles opposite to equal sides in a triangle are equal)

Thus, F=E=40°
