    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

    does that help you determine which triangles are congruent?

    The line down the middle is the angle bisector

    does it matter how I name the congruent triangles

    like for example triangle B,A,D or would it be D,A,B

    that's the same triangle. As long as you have the same three letters, the order of the letters does not matter

    however, this line of thinking doesn't apply with angles. The order of the letters changes the angle
