The option that is a missing step of the proof of ∠D = ∠F is option C (Imaged attached) which is C, ∠DEO ≅ ∠FEO.
What is the missing step of the proof about?
In any triangle, the angle bisector of an angle is known to be that straight line that shares the angle into two said equal or congruent angles.
Note that ∠D = ∠F
The bisector EO is said to bisects the angle ∠DEF and an interior angle of ΔDEF.
So this implies that the angle is divided into 2 equal angles and the option that fit into this is ∠DEO ≅ ∠FEO
So, The option that is a missing step of the proof of ∠D = ∠F is option C (Imaged attached) which is C, ∠DEO ≅ ∠FEO.
