Best ResponseYou've already chosen the best response.0Given: Base ∡BAC and ∡ACB are congruent. Prove: ∆ABC is an isosceles triangle. When completed, the following paragraph proves that is congruent to making ∆ABC an isosceles triangle. Construct a perpendicular bisector from point B to . Label the point of intersection between this perpendicular bisector and 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. is congruent to by _______1________. ∆BAD is congruent to ∆BCD by the _______2________. is congruent to because congruent parts of congruent triangles are congruent (CPCTC). Consequently, ∆ABC is isosceles by definition of an isosceles triangle.

Best ResponseYou've already chosen the best response.0When completed, the following paragraph proves that line AB is congruent to line BC making ∆ABC an isosceles triangle. Construct a perpendicular bisector from point B to line AC. Label the point of intersection between this perpendicular bisector and line 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 AD is congruent to line DC by _______1________. ∆BAD is congruent to ∆BCD by the _______2________. line AB is congruent to line BC because congruent parts of congruent triangles are congruent (CPCTC). Consequently, ∆ABC is isosceles by definition of an isosceles triangle.
