    I need help with proofs

    This is A link to The picture of the chart the questions are based off of

    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

    B. Segment GH bisects segment EF( Again tried another word the horizontal line with vertical one going through the center)

    C. H is the midpoint of .sefment EF

    D. Segment GH is congruent to GH

    17. The best reason for statement 11 of this proof is

    A.congruent angles form congruent segments
    B.definition of perpendicular segments
    C.definition of a midpoint
    D.reflexive property
    18. The best reason for statement 14 of this proof is

    A.substitution property of equality
    B.definition of congruent segments
    C.CPCTC
    D.given
    19. The best reason for statement 16 of this proof is

    A.SSS
    B.SAS
    C.ASA
    D.AAS
    20. The best reason for statement 17 of this proof is

    A.substitution property of congruence
    B.definition of congruent segments
    C.CPCTC
    D.definition of a median

    OK, like I said yesterday. These are pretty basic and you don't seem to be getting any of this. You will need lots of help. Do not despair because there are plenty of ways you can get this stuff. We all struggle from time to time so don't give up.

    First of all the symbol you referred to means perpendicular: horizontal line with a vertical line going through the middle.

    That is not correct for #14, the correct answer is C. A median connects the opposite angle to the midpoint of the line segment.

    Next answer is: definition of a midpoint (Get it from the above statement)

    Next answer should be: C. H is the midpoint of segment EF (Please see the above two statements)

    #17: C.definition of a midpoint

    #18: A.substitution property of equality (This is an equality statement and none of the other answers make sense. So you can figure this one out by elimination)

    #19: B.SAS You have AB congruent to EF, then angle A congruent to angle E, and finally you proved AD congruent to EH. Do you see the reasoning? Side, Angle, Side

    Finally #20 is C.CPCTC

    Please give me some feedback on if you are understanding my explanations. There are many different approaches to teaching and learning this stuff. So if you aren't clear, put in some work and I'll help.
