MEDAL, FAN, and TESTIMONIAL 4 HELP PLZZZ!!!!!!!!!

Answer 1

Given: Base ∡BAC and ∡ACB are congruent.

Prove: ∆ABC is an isosceles triangle.

When completed, the following paragraph proves that Line segment AB is congruent to Line segment BC making ∆ABC 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.

∆BAD is congruent to ∆BCD by the _______1________.
Line segment AB is congruent to Line segment BC because _______2________.
Consequently, ∆ABC is isosceles by definition of an isosceles triangle.
