- burns complete the missing parts of the paragraph proof. given: adfe is isosceles with base fe; fb ec. prove: adfb - adec d we know that triangle dfe is isosceles with base fe and that segment fb is congruent to segment ec because segment df is congruent to segment by the definition of isosceles triangle. since these segments are congruent, the base angles, angles are congruent by the isosceles triangle theorem. therefore, triangles are congruent by sas. f c be Get the answer
