Which angle in def has the largest measure

C. F                     has the largest measure

The largest angle in  Δ DEF is ∠F.

Step-by-step explanation:

We have given a triangle DEF in the picture.

In Δ DEF

DE=4  units

EF=CF=3 units

Clearly, 4>3

Therefore, DE is the largest side with side length 4 units.

We know that the angle opposite to the larger side of a triangle is the larger angle .

Since , ∠F is the angle opposite to the largest side DE.

Hence, the largest angle in  Δ DEF is ∠F .
