I need help with another Geometry question?
what do you need help with?
Ok now I need help
You didn't post any instructions
yes I know I was kicked off earlier
In ΔABC shown below, Line segment AB is congruent to Line segment BC: Triangle ABC, where sides AB and CB are congruent Given: line segment AB≅line segment BC Prove: The base angles of an isosceles triangle are congruent. The two-column proof with missing statement proves the base angles of an isosceles triangle are congruent: Statement Reason 1. segment BD is an angle bisector of ∠ABC. 1. by Construction 2. ∠ABD ≅ ∠CBD 2. Definition of an Angle Bisector 3. segment BD ≅ segment BD 3. Reflexive Property 4. 4. Side-Angle-Side (SAS) Postulate 5. ∠BAC ≅ ∠BCA 5. CPCTC Which statement can be used to fill in the numbered blank space? ΔDAB ≅ ΔDBC ΔABD ≅ ΔABC ΔABC ≅ ΔCBD ΔABD ≅ ΔCBD
I was kicked off the computer by a family member
this is my homework for geometry
