Question

What is the reason for statement 3 in this proof?

definition of angle bisector
Alternate Interior Angles Theorem
Corresponding Angles Theorem
Corresponding angles of congruent triangles are congruent.
Statement Reason
1. Let ΔABC be an isosceles
triangle where AB = BC. given
2. Create point D on side AC¯¯¯¯¯ so
that BD¯¯¯¯¯ bisects ∠ABC as shown. constructing an angle bisector
3. m∠ABD=m∠CBD
4. BD = BD Reflexive Property of Equality
5. ΔABD≅ΔCBD SAS
6. m∠BAC=m∠BCA Corresponding angles of
