Question

I need help.

What are the missing reasons in the proof?
Given:▱ABCD with diagonal line segment BD
Prove: Triangle ABD is congruent to triangle CDB

Diagram will be in the comments.

Statements:

Line segment AB is parallel to line segment CD
Reason:???

Angle ABD is congruent to angle CDB
Reason: ???

Triangle ABD is congruent to triangle CDB
Reason: ???

Answer 1

@Piggiepigpigs Can you help me please?

Answer 2

yeah give a second :)

Answer 3

Opposite sides are equal in a rhombus
side AD = side BC
side AB = side DC
side AC = side AC
These two trianlges are congruent by SSS

Answer 4

@Fang02 does that help

Answer 5

This is for triangles ABD is congruent to CDB, correct?
I kind of get it. Why is AC congruent to AC? There is no line connecting the two unless you go through the other sides.

Answer 6

Yes I took this quiz and got a 29/30 I got a 100% on this problem

Answer 7

Okay, I do trust you.

Answer 8

My bad AC=AC is supposed to be DB=BD sorry for the mistype

Answer 9

Okay, I understand that better.

Answer 10

Oh wait nevermind are you sure that the diagnol is n the right place because for me it connectes AC to AC but for you it connects DB to BD

Answer 11

Yes, I am certain. This question is in the "Proving That a Quadrilateral is a Parallelogram Quiz."

Answer 12

I know I have the same quiz except for me the last question is a little different. The correct answer is DB=BD :D

Answer 13

Okay, I need the reasons why they are like that though.

Answer 14

Reflexive property

Answer 15

I know that one.
The following is what I need help with.
Line segment AB is parallel to line segment CD
Reason: ?

Angle ABD is congruent to angle CDB
Reason: ?

Triangle ABD is congruent to triangle CDB
Reason: ?

Answer 16

The reasons for the first one is because opposite sides of rhombuses are congruent
The reason for the second one is since the anlges in a rhombus are congruent when you draw a line through it (reflecive property) it cuts the angles into equal parts making them congruent
The reason for the third one is SAS

Answer 17

@Fang02 Is that what you wanted

Answer 18

Yes, thank you very much!

Answer 19

Your welcome! :D

Answer 20

:D

Answer 21

What other classes are you in

Answer 22

I'm only in geometry through Connections Academy.
However, I always take Health, English 1, World History, and Earth Science.

Answer 23

What do you mean you always take those classes?

Answer 24

I don't understand.

Answer 25

Oh sorry. I typed the wrong thing.
I meant "However, I *also"

Answer 26

You said that you always take Health, English 1, World History, and Earth Science. What does that mean? Are you trying to say that you are taking those classes right now

Answer 27

Ok where do you take those classes at?

Answer 28

Two other online schools

Answer 29

Two other online schools

Answer 30

Why dont you just take them all at one school?

Answer 31

Each school teaches certain classes differently for me. For instance, one school may teach math with textbooks while another teaches it through tutorials or a lot of practice problems and such.

Answer 32

Oh that makes sense. What other two school are you going to?

Answer 33

Aventa and FLVS. What about you?

Answer 34

I wanted to go to two different online schools but when I signed up connections told me that I could only be in one online school at a time

Answer 35

Oh I didn't know that.

Answer 36

Yeah neither did I until I signed up but I dont mind because the two schools that I wanted to go to had different graduation requirments

Answer 37

I'm going through my school district, so perhaps that's why it differs

Answer 38

That's good. :)

Answer 39

yeah why are you taking earth science. I took that class in 7th grade

Answer 40

I took it back in elementary school, but this time it is required for me to graduate for a high school credit.

Answer 41

Oh that's interesting. I have to take chemistry to graduate or AP earth science. I dont want to take chemistry so I am going to take AP earth science

Answer 42

Cool, good luck! I think I have to take both chemistry and biology. I know biology for sure though.

Answer 43

I dont think that you have to take all of those science classes. To graduate from high school you need three science classes. one would be earth science biology and the third physical science

Answer 44

Oh okay.

Answer 45

You will probably want to take biology because it is easier than chemistry

Answer 46

I heard that biology is rather difficult and a lot of people have trouble with it lol. I don't mind which ever one I have to take. I did an assignment dealing with some of the elements in the periodic table and I understood it. :)

Answer 47

Well if you find that easy then you might actually like chemistry more than biology

Answer 48

Maybe. I'll be right back.

Answer 49

Ok

Answer 50

I am back. Sorry for the wait.
