The appropriate options to fit in the circle regarding the proof will be:
- substitute steps 9 and 10.
- Side-side-side congruence 2, 5, and 6.
- CDF = CEF as they length of the same segment
How to illustrate the circle?
From the information given, it should be noted that the circle centered at point C passes through points D and E and the circles passing through point F, centered at points D and E, have radii of length DF.
Here, it should be noted that the side-side-side congruence is illustrated for 2, 5, and 6. This illustrates that the will have the same lengths for their sides as they're equal.
Therefore, the correct options are illustrated above.
