14. The best statement for reason 6 of this proof is

A. Angle Acd is congruent to angle BCD

B. Segment CD is the midpoint(i think the symbol means mid point it is a horizontal line with a vertical line going through the middle) of segment AB

C.D is the midpoint of segment AB

D. Segment CD is congruent to CD(that is not a typo) .

15. The best reason for statement 7 of this proof is

congruent angles form congruent segments

definition of perpendicular segments

definition of a midpoint

reflexive property

16. The best statement for reason 10 of this proof is

A. Angle EGH is congruent to angle FGH
