Question

Match the reasons with the statements in the proof to prove DF = EF given that DEF is a triangle by definition and angles 3 and 4 are equal.



Given:
△DEF
∠3 = ∠4

Prove:
DF = EF

1. ∠3 = ∠4
Two Angles Supplementary to Equal Angles are Equal to Each Other
2. ∠1 and ∠3 are supplementary

∠2 and ∠4 are supplementary
If the Two Angles of a Triangle are Equal, then the Sides Opposite those Angles are also Equal
3. ∠1 = ∠2
Exterior Sides are in Opposite Rays
4. DF = EF
Given

Answer 1

do you can draw this triangle ?
