Please help!! Select the two reasons which fit best in lines 1 and 2 of the proof (given and details in photo) A: 1.) Vertical Angles are congruent
2.) SSS Congruence Postulate
B: 1.) Definition of Angle Bisectors
2.) SAS Congruence Postulate
C: 1.) Vertical Angles are congruent
2.) AAS Congruence Postulate
D. 1.) Vertical Angles are congruent
2.) SAS Congruence Postulate

D

Step-by-step explanation:

Line 1: Since these angles are vertical, they are congruent

Line 2: We have 2 sides and an angle in between them so it is SAS

This means the answer is D.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
