Step-by-step explanation:
1. DF≅EF ⇒ Reflexive property
2. ∠1≅∠2 ⇒Given
3.FG bisects ∠DFE ⇒Definition of a bisector
4. FG ≅ FG ⇒Given
5.ΔDFG ≅ΔEFG-SAS Congruence
The reflexive property of congruence simple means that any geometric figure is equal to itself. Line DF equals line FE because triangle ΔDFG≅EFG
A line segment that divides a angle into two equal parts in called an angle bisector. Line segment FG is bisects angle ∠DFE
The Side Angle Side Postulate requires that two sides and included angle of one triangle are congruent to two sides and included angle of another triangle. In this case, angle ∠1 , ∠D and side DF equals ∠2, ∠E and side FE
