Complete the missing parts of the paragraph proof.
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.
