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
"1. segment BD is an angle bisector of ∠ABC. 1. by Construction" |dw:1433203580503:dw|
does that help you determine which triangles are congruent?
The line down the middle is the angle bisector
yes I think
does it matter how I name the congruent triangles
what do you mean?
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
