What is the justification?

• reflexive property

• if a point is bisected, then congruent <'s

• if a point is a midpoint, then it divides the segment into 2 = segments

• substitution property

Which postulate or definition states that
m∠ADB + m∠BDC = m∠ADC?

• Segment Addition Postulate
• Angle Addition Postulate
• Definition of Angle Bisector
• Definition of Congruent Angles

If B is the midpoint of AC, then AB ≅ BC.

• Definition of Congruent Segments
• Definition of Midpoint
• Vertical Angles Theorem
• Definition of Angle Bisector

∠4 = ∠4

• Substitution Property of Equality
• Reflexive Property of Equality
• Symmetric Property of Equality
• Transitive Property of Equality

If ∠A and ∠B are complementary,
then m∠A + m∠B = 90°.

• Definition of Supplementary Angles
• Angle Addition Postulate
• Definition of Right Angle
• Definition of Complementary Angles

If ∠1 and ∠2 are supplementary,

then m∠1 + m∠2 = 180°.

• If <'s are supplementary, then they add up to 180°

• Angle Addition Postulate

• Vertical Angles are congruent

• Definition of linear pair

If ∠1 = ∠2 and ∠2 = ∠3, then ∠1 = ∠3.

• Addition Property of Equality
• Symmetric Property of Equality
• Reflexive Property of Equality
• Transitive Property of Equality
