Question

HELP PLEASE!!!
What is the next step in the given proof?
Given: AB = CE
CD = EF
Prove:
AB = DF


I'll post the image below

Answer 1

Statement: AB = DF
Reason: Substitution Property of Equality

Statement: DE = DE
Reason: Subtraction Property of Equality

Statement: CE = DF
Reason: Transitive Property of Equality

Statement: CD = DE
Reason: Substitution Property of Equality

Statement: CE = DE + EF
Reason: Transitive Property of Equality

Answer 2

I know the 4th statement is false

Answer 3

The 5th one is wrong too I think. So now I have to look at the first 3

Answer 4

I think it is the first one. Can someone please help me

Answer 5

@magepker728

Answer 6

I don't think its Transitive Property of Equality because the segments aren't equal.

Answer 7

@ganeshie8 could you help me please

Answer 8

I think this is the answer using substitution property

Answer 9

@welshfella could you help me please?

Answer 10

've never come across these reasons before

Answer 11

I haven't either and i reread the lesson and couldn't find anything so i googled what the reasons meant.

Answer 12

If you didn't have the reasons which wouild you believe it to be? The first?

Answer 13

actually the first one is wrong too

Answer 14

that is what i am suppose to prove

Answer 15

CE=DF

Answer 16

i would prove it this way
AB = CE Given
CD = EF given
CE = CD + DE
DF = EF + DE
but since CD = EF then
DF = CD + DE
so
CE = DF
but AB = CE
therefore AB = DF

Answer 17

lol this reminds me of which came first?

Answer 18

i think line 5 and 6 could be called the substitution property of equality

Answer 19

lo! yes

I dont see why names are given to these things though A lot of it is just common sense. I might be wrong but I dont think they teach them in the UK

Answer 20

- i certainly havn'e been taught that way (Of course that was a long time ago!!)

Answer 21

i would go with A but im not sure

Answer 22

If you had to choose which one would you choose?
Statement: CE = DF
Reason: Transitive Property of Equality

Answer 23

- yea thats a point Being both eqqual to the same thing - that would be a transitive thing

Answer 24

sorry i cant be of more help.

Answer 25

thats ok i really appreciate you trying its hard to get help on here sometimes. Thank you!!!!
