When completed (fill in the bank), the following paragraph proves that ab is congruent to bc making abc an isosceles triangle

Given: Base ∠BAC and ∠ACB are congruent.

Prove: ΔABC is an isosceles triangle.

When completed (fill in the blanks), the following paragraph proves that Line segment AB is congruent to Line segment BC making ΔABC an isosceles triangle.

Construct a perpendicular bisector from point B to Line segment AC.  

Label the point of intersection between this perpendicular bisector and Line segment AC as point D.  

m∠BDA and m∠BDC is 90° by the definition of a perpendicular bisector.  

∠BDA is congruent to ∠BDC by the definition of congruent angles.  

Line segment AD is congruent to Line segment DC by by the definition of a perpendicular bisector.  

ΔBAD is congruent to ΔBCD by the 1.  

Line segment AB is congruent to Line segment BC because 2.  

Consequently, ΔABC is isosceles by definition of an isosceles triangle.
